COBOL has nested programs. All callable routines are programs. As part of a year 2000 project I created the date subroutine as a program in a copybook. The program library had it as a program with the only code a COPY statement copying the copybook with the same name as the program. This took advantage of the nested COPY capability so that the copybook could contain copy statements. This allowed the date routine to be either included as source in the CALLing program or as a separate module. Look up nested programs in the manual.
