Message:

Additional space optimizations, including making IdleProcessing an option in MENUEVENT. Note the fall-through from one file to another, but that there are assembler checks to ensure the proper linkage is maintained. First version of StringsCompress.pl, a perl script to make StringsCompressed.asm from Strings.asm.
