Created On:  7 July 2010 Problem: We created a COBOL COM Server program using the Net Express Class Wizard and have a file defined within the Input-Output section within the Object itself.  When trying to open the file for output a file status 9/004 "Invalid Filename" is returned. Resolution: This is happening due to the location of the file definition within the COM Server program.  Although it will compile cleanly, file definitions cannot be placed within the Instance Object itself.  Files need to be defined as shown in the following example:$set ooctrl( p)                                                   class-id. testobj           &nbs

Created On:  19 May 2010 Problem: There exists documentation that shows how to pass an argument in a C$JAVA CALL, but it's not easy to understand the correct syntax when more arguments are involved. Resolution: This article explains how to pass more than one single argument in a C$JAVA CALL, when a COBOL program interhoperates with a JAVA class. You can pass as many arguments as the method requires. You will need to specify the correct method signature, which you can obtain using the Java class dissassembler utility "javap":$ javap -s myclassLet's say you've got a method that takes two Strings and three numbers as arguments, and returns an integer.The signature would be "(Ljava/lang/String;Ljava/lang/String;III)I" (this will be returned by javap).CALL "C$JAVA" USING CJAVA-CALL,                          &n

Created On:  22 June 2010 Problem: The ASLM Semaphore Error 1002 was received when a Net Express 5.1 executable was called from within a trigger program. Resolution: The error occurred because a previous version of Net Express' runtime files were used during execution instead of the current version the application uses.For example, a user originally built an .exe with Net Express 3.1.  They upgraded their environment to Net Express 5.1 and recompiled their application with Net Express 5.1.  However, they inadvertently copied a runtime .dll into the Net Express 5.1 Bin directory.  Including a prior version .dll in the Bin directory will generate an Error 1002.  Remove any .dll's that were copied over into the Bin directory to eliminate the error.

Created On:  23 June 2010 Problem: When compiling using the Net Express IDE the error "Micro Focus License Manager Service not Running" is displayed in the output window. Resolution: Check the setting of the COBDIR environment variable either in the computers environment or in the project properties under the IDE settings.This error will occur if COBDIR is set to point to an invalid location or it is overwriting the current value in the environment which is the default location of "C:\\Program Files\\Micro Focus\\Studio Enterprise Edition 6.0\\base\\bin".COBDIR should not point to the location and name of the directives file cobol.dir.It should instead be set to the folder name where your executables reside if they are .int or .gnt.When COBDIR is set you should always include the current setting so that the new setting will be appended to the current one instead of overwriting it.Example:COBDIRC:\\testdir;%COBDIR%In most cases you do not need to set

Created On:  05 October 2009 Problem: Starting an ASP.NET program can causes a delay of 90 seconds before even the smallest "Hello COBOL world"-program begins execution. This might happen, when the computer has no access to the external internet Microsoft Network Monitor shows that the program vainly tries to access crl.verisign.net on port 80 several times. Resolution: The web address crl.verisign.net belongs to the Certificate Revocation List @ VeriSign. The program tries to verify whether its certificate has been revoked or not. 1. A certificate revocation list (CRL) for the site could be manually imported, following:http://technet.microsoft.com/en-us/library/aa996972(EXCHG.65).aspxhttp://www.amug.org/~glguerin/opinion/revocation.html#obtaining 2.

Created On:  20 October 2009 Problem: In a migration project the WRITE statement behaves differently from the origin. Resolution: The WRITE statement changes its behavior dependent on the selected dialect. When using:      $set dialect"OSVS" or      $set dialect"ENTCOBOL"the statement            WRITE RECwill delete the REC in       FD  MYFILE LABEL RECORDS OMITTED.01 REC PIC X(80).accordingly to the OSVS COBOL resp. Enterprise COBOL on the mainframe. When using      *set dialect"MF"the statement            WRITE RECwill keep REC unchanged. If the dialect is unsupported, where the sources came from, either choose a better dialect to be closer to the origin or some code may need to be added to the WRITE statement. Incident

Created On:  01 October 2009 Problem: The runtime routine CBL_DIR_SCAN_READ returns a value of 127 which is not a file status code as described in the Net Express help. Resolution: Here are 4 possibilities to get the returncode 127 in CBL_DIR_SCAN_READ even the CBL_DIR_SCAN_START returns 0 (o.k.) (there might be more…): 1. When wildcards are used in CBL_DIR_SCAN_START the appropriate FLAG must be set in CBL_DIR_SCAN_START.2. When quotes are used to specify the search pattern in CBL_DIR_SCAN_START (see: KB 1444).3. When pattern-length in CBL_DIR_SCAN_START does not specify the real length of the pattern but e.g. the length of the buffer, it might cause a 127.4. When the handle in CALL “CBL_DIR_SCAN_READ” is not passed BY REFERENCE.

Created On:  19 March 2010 Problem: Compiling This error occurs while Animating a COBOL program. This error occurs when the user has set the COBTERMINFO environment variable to point to a customized terminfo file. Resolution: When running under the control of the Animator any screen output is cached in memory. If you swap to the user screen (i.e. by pressing F2 or by executing an ACCEPT), the contents of the cached screen are displayed. The program has no terminal of its own because it's under the control of the animator. So, when the program writes to the terminal, it is actually passing terminal sequences to the animator to be decoded and cached. The Animator uses a generic terminal definition called 'mfdebug', which defines all the capabilities required This error only occurs if a customer is using a different terminfo directory, or has deleted some files from the Micro Focus provided one. When a process is being debugged by Animator, if the application then

Created On:  8 June 2010 Problem: The Net Express documentation shows that the display method can be called on the Java Exception object in order to output the error text to the console.     entry "Jexception" using lnkException.           invoke lnkException "display" How does one modify this example so that the text can be accessed in a move statement to a COBOL pic x field? Resolution: The javasup class must be used to accomplish this task. Try the following as the main program:      $set ooctrl ( p-f)       program-id. ExceptionCatcher.        class-control.           SimpleClass is class "$JAVA$SimpleClass"           EntryCallback is class "entrycll"  &n

Created On:  8 June 2010 Problem: Question on use of C# string specifier @:In the C# code snippet below:            DirectoryInfo info = new DirectoryInfo(@"C:\\Documents and Settings");The @ specifier indicates a verbatim string in C#. Resolution: Here is the definition from the C# programming guide: Use verbatim strings for convenience and better readability when the string text contains backslash characters, for example in file paths. Because verbatim strings preserve new line characters as part of the string text, they can be used to initialize multiline strings. Use double quotation marks to embed a quotation mark inside a verbatim string. The following example shows some common uses for verbatim strings: C#  Copy Code          string filePath = @"C:\\Users\\scoleridge\\Documents\\";         //Output: C:\\User

Created On:  8 June 2010 Problem: While using Visual Studio to develop managed COBOL applications the Intellisense of Visual Studio stops working. Resolution: The items to check in the Visual Studio IDE are the options for the Text Editor under Tools->Options. Under heading COBOL->General, Auto list members and Parameter information should be checked and under Miscellaneous, AutoOutlining, Customize Editor for COBOL and Enable background...should all be True.You might try toggling these off and on so the IDE recognizes them.

Created On:  7 June 2010 Problem: When calling a COM interface that was generated using the IMTK, (Interface Mapper Toolkit), from a .NET client program sometimes the error "MFCLBINP Error 402" is reported when the interface method is called.This occurs when the unmanaged COBOL program which will be called by the COM interface is a Dynamic Link Library (.DLL) and it is not linked to the multi-threaded runtime system. Resolution: This only occurs if a .DLL is being called. .int and .gnt programs do not exhibit this behavior.Please ensure that the .DLL to be called from the generated COM interface is linked to the multi-threaded run-time system.If this .DLL is created in a Net Express project then using the IDE, select Project->Build Settings->Link Settings and check the Multi-threaded option.If you are creating this .DLL using cbllink then use the option -rM.

Created On:  14 June 2010 Problem: I am unable to connect more than ten WOW Thin Client sessions to my Linux server. Resolution: This issue is caused by a change to the xinetd service daemon defaults on some Linux distributions.The "per_source" attribute specifies the maximum number of instances allowed to a single source IP address.  On some Linux variants this default is set to a value of 10. In order to address this issue you will need to modify your "rpcplus" xinetd configuration file ( /etc/xinetd.d/rpcplus ) and add the "per_source" attribute.  For example: service rpcplusper_source  = UNLIMITEDYou will need to restart the xinetd daemon after making these changes.  Please check your Linux distribution's manuals for information on how to restart xinetd.

Created On:  16 June 2010 Problem: I need a display that is larger than the default 80 columns by 25 rows. Resolution: You can use the TERM-ATTR "COLUMNS" and "ROWS" configuration keywords to increase the number of columns and rows that the Runtime will display on the terminal.  These configuration records will need to be added to your RM/COBOL Runtime configuration file or placed in a new RM/COBOL configuration file.For example, the following record in your configuration file will yield a screen that is 100 columns wide with 30 rows: TERM-ATTR COLUMNS=100 ROWS=30For more information regarding terminal configuration, please see "Chapter 10: Configuration" in the RM/COBOL User's Guide.  You can obtain the RM/COBOL User's Guide from our web site at:  http://supportline.microfocus.com/Documentation/RMCobol.asp Incident #2457869 Old KB# 31190

Created On:  7 June 2010 Problem: When working with COBOL files that are defined as Heap Files using the Filetype"14" directive, a close on the file would sometimes result in a bad file status such as a 9/013 "File not Found" error being returned.There is a problem with the logic in the File Handler for the CLOSE statement handling of Heapfiles where the return-code was being checked prior to the actual close operation being performed. This means that if there was a bad status code from a previous operation in the File Handler then the error would actually be reported for the close because the status code area was not cleared out. So the close wasn't really failing, it was just been reported as bad because there was another operation that actually failed. Resolution: This problem has been fixed in Net Express 5.1 Wrappack 4 Hotfix 5 and above. Incident #2448545 Old KB# 31153
