When mixing languages within an application, presenting the desired
main routine to the link-edit process first nominates it as the entry
point. You can specify only one main routine.
To get
Language Environment's
support in using pre-
Language Environment C – COBOL
ILC applications, you must relink-edit these applications to replace
old HLL library routines with
Language Environment routines.
Relink-editing ILC applications of any language combination is usually
required, with the following exceptions:
- Any PL/I – COBOL ILC applications relink-edited using the migration
aid provided by OS PL/I Version 2 Release 3. (See the IBM Enterprise PL/I for z/OS library for details.) The PTF numbers
for the migration aid are UN76954 and UN76955.
- Any PL/I – C ILC applications.
- Any COBOL – C ILC applications relink-edited using the migration
aid provided by the C/370™ Version
2 Library. This migration aid was delivered in the fix for APAR PN74931.
For more information, see z/OS Language Environment Writing Interlanguage Communication Applications, z/OS Language Environment Runtime Application Migration Guide,
and the migration guides for your primary HLL.
