The math package in the ZIPfile attached to EDN BBS /DI_SIG #1570 allows 6805 mCs to perform unsigned, 32-bit math. The subroutines contain the source code for add, subtract, multiply, and divide routines.
The C command-line collector in EDN BBS /DI_SIG #1410 classifies everything on the command line after the program's name. With this routine, users no longer have to bother with abstruse parser-friendly restrictions, such as just where to put flags in the command line.
