MAC QB 1.00 README: If CHAIN "Out of Memory," Change Stack (34347)

SUMMARY

The following information needs to be added to Page 540 in Appendix F of the "Microsoft QuickBasic 1.00 Basic Language Reference." This information was taken from the README file from the release disk:

In programs with CHAINed modules, you may have to change the stack size for the compiled application if you get "error 7" at the CHAIN statement. Compile all the modules with the "Create Program List File" option on and look in the listings under STORAGE in the "Symbol and Label Tables for: MAIN." Your main module needs to clear enough stack space for the largest STORAGE entry with code similar to this:

  '   As above, heap& is the heap space. stack& is the stack space
  heap&=100*1024&    'fill in the actual heap& you want to leave
  stack&=10000&      'use value from 'lst' file for the largest module
  IF SYSTEM(4) THEN  'compiled
      CLEAR,FRE(0)+FRE(-1)-heap&-stack&,stack&
  ELSE    'interpreted
      CLEAR,FRE(0)+FRE(-1)-heap&
  END IF
