Can you specify an EXEC SQL INCLUDE statement using an environment variable?

Problem:

Can you specify an EXEC SQL INCLUDE statement using an environment variable, for example

EXEC SQL INCLUDE $MYENV\\MYCOPY END-EXEC

where MYENV points to the directory where the MYCOPY copybook is located.

Resolution:

You can do this by additionally using the CP preprocessor. Add the P(cp) compiler directive to enable use of this preprocessor.
