I compiled an existing QB45 program into QB64.  The QB45 program runs well.  This program would not execute originally because the source code used too much memory.  I then broke the program into subroutines and the program executes well in QB45.  QB64 when it compiles takes QB45 subroutines and places them into one executable code main module.  Subs are contained within the QB64 main code module.  When the compile happened, the code would not run because no memory for the code.  So this is where I started originally in QB45 before breaking the code into sub-routines which are separate from the main module in QB45 but added to the main module in QB64.  Is there a way to run subs in QB64 so they are not added to the main module so the main will execute without not enough memory error?
