Runtime products required for program linkage

Since the CRTE versions are upwardly compatible, at least the highest of each required CRTE versions must be used for program linkage if the individual programs presuppose different CRTE versions.

For details on the required CRTE version please refer to the release notes of the relevant compilers.

When linking with programs written in other languages (ASSEMBH V1.2 and higher, FOR1 V2.2, Pascal-XT V2.2 and higher, PLI1 V4.2 and higher, RPG3 V4.0 and higher), the runtime system for the languages involved must also be linked.
