The Create Control Language Program (CRTCLPGM) command allows you to compile CL source programs to use on a previous release by using the target release (TGTRLS) parameter.
The TGTRLS parameter specifies on which release of the i5/OS™ licensed program the CL program object created intends to run. You can specify *CURRENT, *PRV, or a specific release level.
A CL program compiled with TGTRLS(*CURRENT) runs only on the current release or later releases of the operating system. A CL program compiled with a specified TGTRLS value other than *CURRENT can run on the specified release value and on later releases.
