This chapter describes factors that affect the compatibility of OS PL/I object and load modules in Language Environment. The discussions include both OS PL/I Version 1 and OS PL/I Version 2 object and load modules.
All of the library routines in a load module must be from the same release of the run-time library. For example, Language Environment stubs, OS PL/I Shared Library stubs, and OS PL/I resident library routines cannot exist in the same load module.
To find out what tools are available to help you migrate your libraries to the Language Environment run-time environment, see Appendix A. Conversion and Migration Aids.
