The create data (*CRTDTA) associated with an ILE program or module may make up more than half of the object's size. By removing or compressing this data, you will reduce the secondary storage requirements for your programs significantly.
If you remove the data, ensure that you have all source required to create the program or have a comparable program object with CRTDATA. Otherwise you will not be able to change the object.
An alternative is to compress the object, using the Compress Object (CPROBJ) command. A compressed object takes up less system storage than an uncompressed one. If the compressed program is called, the part of the object containing the runnable code is automatically decompressed. You can also decompress a compressed object by using the Decompress Object (DCPOBJ) command.
