If your path definition includes the directory containing
program by simply typing its name:
% a.out
If the executable image is not in your current directory path, specify the directory
path in addition to the file name.
The COPY Statement and Libraries
As you write a program, you can use the COPY statement in your source program
to include text from another file. With the COPY statement, separate programs
can share common source text kept in libraries, reducing development and testing
time as well as storage. The Compaq COBOL Reference Manual explains how to
use the COPY statement.
Special Considerations for Routines Named ''main''
If you have a program or routine named ''main,'' declared either in a Compaq
COBOL or other module, your application may not work correctly. The Compaq
COBOL library contains a routine named ''main,'' which initializes the run-time
environment for the CALL by data name statements, extended ACCEPT and
DISPLAY statements, and some error handling. When your application also
declares a ''main,'' your routine preempts the Compaq COBOL routine, and the
run-time initialization is not performed.
