Migrating COBOL programs to Language Environment
Table 1 contains a subset of COBOL compatibility exceptions.
| To migrate: | You need to: |
|---|---|
| OS/VS COBOL programs mixed with assembler under non-CICS | Run in a single run unit (SVC LINK is not allowed). |
| OS/VS COBOL programs that use ILC with PL/I | Upgrade the COBOL source code to Enterprise COBOL for z/OS or COBOL for OS/390 & VM. |
| OS/VS COBOL programs that use ILC with FORTRAN | Upgrade the COBOL source code to Enterprise COBOL for z/OS or COBOL for OS/390 & VM. |
| VS COBOL II programs that use ILC with C or PL/I | See Table 1 for information about migration aids for each language. |
Restriction: Do not install more than one library for
a language in the LNKLST or LPALST. You should not concatenate pre-Language Environment runtime
libraries in the LNKLST.
For detailed migration information about LNKLST concatenation and COBOL, see the appropriate version of the COBOL migration guide in the Enterprise COBOL for z/OS library.
