I'm being invaded by assembler bugs ! Message-ID: <2252@gold.gvg.tek.com> Date: 2 May 91 19:39:44 GMT Organization: Grass Valley Group, Grass Valley, CA Lines: 12 I've been doing some assembly language programming on my Northstar advantage, and the CP/M 2.0 assembler sometimes 'hangs' - No errors, etc. I have to punch to reset switch. I found that if I sprinkle NOP instructions throughout the source code (and NO other changes), it finally assembles without errors after several trial/error iterations. Does anyone know *what* causes the assembler to hang, and how to *predictably* avoid the bug ? Thanks. grege@gold.gvg.tek.com
