Symbol Table

Hello - I'm having trouble getting the symbol table to load while in the debugger - can someone tell me what I'm doing wrong please?

***There is no symbol table in '/usr/ud/sys/CTLG/m/MV.EMAIL.BUILD.TO.PC.AND.TO.S
B'
!EXEC BASIC MV.BP MV.EMAIL.BUILD.TO.PC.AND.TO.SB -Z2
***Executing UNIDATA command:  BASIC MV.BP MV.EMAIL.BUILD.TO.PC.AND.TO.SB -Z2

Compiling Unibasic: /db1/ud1/PGM/MV.BP/MV.EMAIL.BUILD.TO.PC.AND.TO.SB in mode 'u
'.
compilation finished
!Z MV.BP MV.EMAIL.BUILD.TO.PC.AND.TO.SB
***There is no symbol table in '/usr/ud/sys/CTLG/m/MV.EMAIL.BUILD.TO.PC.AND.TO.S

Kathleen,

I've been testing this internally and this looks like a bug in UniData on all of the current GA versions. I will raise a ticket on this.

Regards,

Jonathan

For reference I have created issue UDT-20602 for this, Kathleen if you want to raise a support ticket with us on this, I can link the bug ticket to the support case in order to keep you and the customer updated on progress on the ticket.

What is my work around? To recompile all programs and recatalog before debugging?

@Grant Boice I noticed a problem in my testing script so I've removed some of the posts on this to tidy up the thread a bit as I did more testing internally and I found a way to make it work to everytime as I could see the assumptions the parser is making with the Z command.

The Z command syntax is Z filename programname catalogname. If no catalogname is specified, catalogname defaults to programname.

Based on these results I will be updating the internal ticket and documentation.

Here are the results of the internal testing

If the program has no catalog entry and you run the program it fails to load the symbol table, the reason for this is that the catalog entry defaults to KH001 from which there is no VOC entry so assumes it's a global catalog entry and attempts to load the symbol type from where the global catalog entry would point to $UDTHOME/sys/CTLG and fails because it cannot find it.

:RUN BP KH001 -D
***DEBUGGER called at line 1 of program BP\\_KH001
!\\*
***There is no symbol table in BP\\_KH001
!EXEC BASIC BP KH001 -Z2
***Executing UNIDATA command:  BASIC BP KH001 -Z2

Compiling Unibasic: BP\\KH001 in mode 'u'.
compilation finished
!Z BP KH001
***Can not find object/catalog file: 'C:\\u2\\ud\\sys\\CTLG\\k\\KH001'.
!E

If the program has a direct catalog entry it works and it finds the VOC entry for KH001 and it resolves to the item in the file that was just compiled and finds the symbol table in that file and loads it succesfully.

:CATALOG BP KH001 DIRECT

:KH001 -D
***DEBUGGER called at line 1 of program BP\\_KH001
!\\*
***There is no symbol table in BP\\_KH001
!EXEC BASIC BP KH001 -Z2
***Executing UNIDATA command:  BASIC BP KH001 -Z2

        C                       variable
        D                       variable
!E

If the program has a local catalog entry, if fails because it tries to load the symbol table from the local catalog which would not have been refreshed by the EXEC BASIC command.

:CATALOG BP KH001 LOCAL

:KH001 -D
***DEBUGGER called at line 1 of program C:\\accounts\\ud\\general\\CTLG\\KH001

!Z BP KH001
***There is no symbol table in 'C:\\accounts\\ud\\general\\CTLG\\KH001'

If the program is globally cataloged it fails because it tries to load the symbol table from the local catalog which would not have been refreshed by the EXEC BASIC command.

:CATALOG BP KH001

:KH001 -D
***DEBUGGER called at line 1 of program C:\\u2\\ud\\sys\\CTLG\\k\\KH001

To get it working for a LOCAL catalog

For a direct run with no catalog, you can catalog it direct or global to get it to work

:RUN BP KH001 -D
***DEBUGGER called at line 1 of program BP\\_KH001
!\\*
***There is no symbol table in BP\\_KH001
!EXEC BASIC BP KH001 -Z2
