Problem:   If the sub-program is called:        CALL "subprog" USING OMITTED OMITTED WS-VAR-3. The following error occurrs: Execution error : file 'subprog.int' error code: 203, pc=225, call=1, seg=0 203     CALL parameter not supplied How do I validate which parameter is omitted to avoid this error? Resolution: The 203 error is correct as you need to test for the presence of each parameter before attempting to modify it in the sub-program. This is done with the following code:       if <variable-name> is not omitted           move ... and so on. Old KB# 5818

Problem: 'Verify Server Settings' returned this error.    Resolution: Norton Internet Security was enabled on the PC and did not for some reason report that it was blocking access to this IP.   When this was resolved, publishing worked OK. Old KB# 5804

Problem: Moved from test to production server - now when client tries to start application it goes right to the ssdisconnect screen Resolution: If you are receiving an immediate ssdissconnect, it usually means it is not reaching the host designated in the project settings. Now that you have moved from test to production - check to see if the host name or IP number is correct - also very important the PORT number -  in the admin\\project  - edit project (application) in question Old KB# 5903#EnterpriseLink#Rumba

Problem: How do I use the RENAME subprogram call? Resolution: Please see the attached file RENAME-EXAMPLE.CBL Attachments: RENAME-EXAMPLE.CBL Old KB# 6125

Problem: Can i get rid of the some of the buttons of the keyboard that appears at the bottom of the page - that appears when you run the customized application. Resolution: In builder, highlight the page you are modifying and do a right click on properties. click on the Display tab, and uncheck the "include button bar" You will then have to place your own buttons on the page, to click on the buttons for each type of keyboard function that may go with the page. Make sure you do a save and flush the cache before running to see the new pages modified, if you dont see the new pages, restart the web service to clear all cache. Old KB# 5899#Rumba#EnterpriseLink

Problem: Is there  a way to delete screens/pages from the repository without having to delete them one by one in Builder ? Resolution: We now provide 2 utilities (batch files) to delete screens and pages. Documentation for command-line batch files to Delete Screens and/or Delete Pages has been added to the EL Wiki in www.enterpriselink.com -> Authors.    Once inside EL Wiki, do a search on "Delete Pages" or "Delete Screens".   Detailed information including the batch files themselves and their operation is given.   Please pay careful attention to the "Note" at the bottom of each entry. For Deleting Screens, the file, DeleteScreens.bat should be executed. It requires two parameters with an optional third parameter. The first parameter is the project-name.   The second parameter is either 1)  the name of a file containing a list of screens (one per line) to be del

Problem: How can I use C$SCRD to Read the Display Screen? Resolution: An example source code file is attached. Attachments: SCRD.CBL Old KB# 6118

Problem: Does EL require DCOM services to be running?  Standards recommend that DCOM be turned off.  Will this affect the way EnterpriseLink is run? Resolution: No, DCOM, Distributed Component Object Model, is not necessary for EntepriseLink. Old KB# 5906#Rumba#EnterpriseLink

Problem: Failed attempt at using Project Manager locked my project. How can I unlock them to use outside of Project Manager? Resolution: Solution without project manangement. Notes: You don't have to actually use the Master Repository at all. Assuming your ELRepository is locked Create a new DNS (mdb)     Administration-> Repository -> Add new DNS -> *.mdb     change the Data Source Name to ELRepositorynew     Choose a new mdb file in a new location Initialize     Administration -> Repository -> schema -> ELRepositorynew -> initialize            Migrate     Administration -> Projects -> migrate projects ->        sources is ELRepository  -> choose your project        destination is

Problem: Unable to populate an empty Net Express project from CA Harvest. Resolution: This seems to be caused by an undocumated feature in CA Harvest prior to version 5.1.2.  Either upgrade to 5.1.2 or 7 of CA Harvest to correct the problem. Old KB# 5793

Problem: When attempting to install Net Express .NET the Visual Studio.Net prerequisite CD asks you to insert cd-1 and then hangs. Resolution: Ensure that you have at least 128MB of RAM on the machine you are installing to. Old KB# 5810

Problem: Unable to debug C and COBOL programs at the same time -- why? Resolution: This is expected as you can only use on hard mode/low-level debugger at a time in Windows.  Both Visual Studio and Net Express use the low-level debugging support i.e. they conflict. Your options to get around this are: 1) Debug the C in Visual Studio and run the COBOL. 2) Run the C from Net Express (Animate Settings) and debug the COBOL. 3) Run the C from the command line and use CBL_DEBUGBREAK. Alternatively, you could switch to .NET where you can have the C and COBOL mixed together within Visual Studio as managed code. Old KB# 5823

Problem: What does C$OSLockInfo Subprogram do? Resolution: C$OSLockInfo returns the PID of the process that has the record locked when a lock request fails. It should be called immediately after a lock request fails. This subprogram is available only under UNIX; there is no Windows equivalent. Calling Sequence: CALL "C$OSLockinfo" USING processid processid is a four-byte, unsigned COMP-4 numeric item.      Old KB# 6123

Problem: How do you right-justify a numeric value? Resolution: If a numeric value is accepted in an alphanumeric field, (which is left- justified) and it needs to be right-justified, try the following code: 01 alpha-item pic x(10). 01 move-item redefines alpha-item pic z(10). 01 num-item pic 9(10). ...     accept alpha-item.     move move-item to num-item.     display num-item. This should cause num-item to be right-justified. A direct move won't work because we pad alphanumeric fields with trailing spaces, and these spaces don't get stripped.      Old KB# 6114

Problem: Why is my data not stored as a numeric? Resolution: If you have a group item, all members of the group are treated as alphanumeric, even those defined as a numeric field. For more information, see the Language Reference Manual, under Data Structures.      Old KB# 6120

Problem: Can symbolic characters be used in an unstring command? Resolution: Yes. See the UNSYMBOL.CBL example program attached. Attachments: UNSYMBOL.CBL Old KB# 6111

Problem: Is there a way to reset a user associated with files that have previously been checked-out in the Project Management Utility?   The customer ran the query to reset the locks (as they had problems checking in and checking out files) which worked fine, i.e., the page is no longer checked out BUT the USER associated with the Checkout is still listed in RED.  Is there a way to reset this? Resolution: A database administrator for the underlying database could issue the following query against the ELMasterRepository ODBC DSN using their favorite SQL tool or via http://localhost/stadmin/query.html :    UPDATE pm_pageinfo    SET checkedoutto = NULL,        checkoutlocation = NULL,        checkoutcomment = NULL,        checkoutdate = NULL    WHERE pageno IN (SELECT pageno FROM pm_p

Problem: Working with IUnknown pointers in an OLESafeArray. If you have an instance of OLESafeArray which contains the OLE type (determined by invoking "getVarType" on the safe array object) VT-UNKNOWN (value 13 in olesafea.cpy copy file), you can use the OLESafeArray "getElement" method to retrieve the pointer value. You can then use the pointer value as a parameter to the olesup "getCOBOLObject" method to return an object reference which you can then work with. Resolution: Working with IUnknown pointers in an OLESafeArray. If you have an instance of OLESafeArray which contains the OLE type (determined by invoking "getVarType" on the safe array object) VT-UNKNOWN (value 13 in olesafea.cpy copy file), you can use the OLESafeArray "getElement" method to retrieve the pointer value.

Problem: Trying to set-up Unix publish by populating the Unix .rhosts file in the home directory with the tcp/ip address of the PC.  The following error is displayed when trying to verify the server settings: The server refused to execute the Server Control Program. Please check your server configuration. rshd: 0826-813 Permission is denied. Resolution: The Net Express documentation contains the following warning in the Unix Option Guide (Appendix A: Installing Samba and SCP): Warning: The .rhosts file must be owned by the user ID that owns the directory and must not be writable by either group or world ( that is, it must have rw-r--r-- permissions). Also, it cannot be a symbolic link. In this case the problem was due to permissions of the .rhosts file being rw-rw-r--. Correct permissions can be set using the following command in the home directory: chmod 644 .rhosts Old KB# 5803

Problem: Is it possible to specify a Y2K pivot date with MFSORT? Resolution: Unfortunately there is no way to specify the Y2K pivot year with MFSORT i.e. where the 20th and 21st centuries start. Old KB# 5800

Problem: A user cannot save a new page in Builder. Resolution: Seems that the memory that EnterpriseLink Builder was trying to access to save the page was unavailable.  Once the user was able to reboot his machine and open Builder and then try to save the page, it worked. Old KB# 5907#EnterpriseLink#Rumba

Problem: Message when running deployed application: "Unable to find COBOL run time" even though Application Server has been installed onto the deployment machine and the PATH and COBDIR environment variables are pointing to the Application Server installation folder. Resolution: If you are deploying EXE's or DLL's it is worthwhile checking to see whether they are built to use Dynamic Binding - as this forces the application to search for the COBOL runtime using the path's set in the Windows registry. If you build them and deploy them to not use Dynamic Binding the the application will look for the COBOL run time using the location set using the PATH and COBDIR  environment variables. Old KB# 5799

Problem: Can you have large numeric data items greater than 18 digits - pic 9(18)? Resolution: The INTLEVEL"4" compiler directive can be used to declare long numeric data fields, PIC clauses greater than PIC 9(18), up to 31 digits. Old KB# 5824

Problem: A VB application needs to run a COBOL console application in the .NET environment.  Pressing a button on a VB form is required to startup a COBOL Console exe that will accept and display. Resolution: One way would be to have a COBOL COM object (a dll) as a proxy between the VB application and the COBOL Console application.  This is the documented method and is the recommended route to take when passing arguments or values between the two languages. Please refer to the documentation on COM in the Getting Started and Distributed Computing books. Please note that you cannot accept and display from a COBOL dll. On the otherhand, you can run a COBOL Console exe directly from the VB with the following statement in the VB code: System.Diagnostics.Process.Start("the COBOL Console exe file") Old KB# 5822

Problem: How can I handle Dates and Null Values in Relativity? Resolution: Some of our Relativity customers have experienced problems with the use of date fields from COBOL applications. The problem primarily occurs because many applications written in COBOL make use of certain field characteristics that cause a date field to be invalid in ODBC applications. For instance, a date field in COBOL that contains spaces or zeroes is perfectly acceptable since the application code can test for those values and take appropriate action. Whereas, when ODBC tools employ a field which is defined as being a date, it must only contain a valid date. As a way around this problem, some Relativity installations have avoided the use of Date Transforms and simply used the date as a numeric field so that the ODBC application avoids any date checking. This solution doesn't overcome all the issues, but it does limit the need for intervention to some degree. All that needs to take place is t
