     All you have to do is change the PERMANENT STORAGE SIZE value located in
the Module Header for RUNB (or Basic09, etc.). On page 22 of the OS9 Technical
Information Manual (Radio Shack's, CoCo OS9), there is a chart showing the
Executable memory Module Format. Relative Byte Offsets H0B and H0C can be
changed using the OS9 Debugger. OS9 uses this value to determine how much
memory is needed to execute a process, unless you override it.
     Just use the debugger to change the Permanent Storage Size value, then use
VERIFY to update the module's CRC checksum value, etc. If you do not want to
use the debugger you can write a simple Basic09 program to SEEK to these
locations, and then change them, on disk. Then you can run Verify against the
changed file.
