COBRT250 Not enough mainframe address space to load or run the program (Fatal)

This program has been compiled with one of the compiler directives AMODE(24) or AMODE(31), which request the program's data division be registered with the Mainframe Pointer Manager. However, there is not enough free mainframe address space to allow this. For example, if you have compiled with the AMODE(24) compiler directive, the total address space required for your program's data division should not exceed 16 megabytes.

Resolution:

Reduce the amount of mainframe address space required by cancelling any other AMODE programs that are not currently in use.
