The /COPY and /INCLUDE directives are identical except that they are handled differently by the SQL precompiler.
The way the /COPY and /INCLUDE directives are handled by the SQL precompiler is different depending on the RPG preprocessor options parameter (RPGPPOPT) specified on the CRTSQLRPGI command. Refer to "Coding SQL statements in ILE RPG applications" in the Embedded SQL Programming topic or the CRTSQLRPGI command in the CL topic for more information.
For more information about these directives, see /COPY or /INCLUDE.
