RE: z80 routines In an effort to avoid re-inventing the wheel, I am looking for pointers to existing z80 assembly math routines. I know of a book titled "6502 assembly language subroutines". Does such a beast exist for the z80 ? Specifically, I need to do +-*/ on ascii strings. Space and speed are critical. Thanks, Jeff Hagen decvax!bunker!jrh

The library SYSLIB3, which is distributed in source code form with ZCPR3, contains several numeric string conversion routines (ASCII text to hex, octal, decimal, and binary and binary to ASCII text in hex, octal, decimal, and binary and math library). It is in 8080 code, so it runs on both 8080s and Z80s. Documentation is in HLP files. Rick -------

Leventhal, and Winthrop Saville. It is published by Osborne/McGraw-Hill, copyright 1983. Topics covered: Arrays, Arithmetic, Bit manipulation, String manipulation, I/O, Interrupts.
