A year ago I began my years' - long quest to learn and implement a high =20 level language just one more time. I chose Jalv2, 'cause it is so=20 similar to Pascal, the only HHL I loved as a young engineer (TP3, in=20 fact, then TP4/5) . So, I wanted to test Jalv2 by rewriting a already-running MPASM=20 application into Jalv2. After about 40 hours spent on a program that=20 only took 12 hours to assemble and debug in MPASM7x a few years ago,=20 I've had to toss in the towel, for now. There is a serious flaw in CASE, but I can't find it. I repeatedly=20 stepped through the compiler output which LOOKED ok using MPLAB8.5 SIM.=20 The code looked goofy (all HLL's look goofy to an ASM programmer) but ran without error in the SIM. But it never did a=20 thing in real time. I then began to systematically strip out routines=20 until it made a few squeaks. The operation I clipped out was the single=20 CASE. I KNOW the problem is in me, but I am very discouraged. I think the=20 answer is some way to place breakpoints in the Jalv2 code. I was unable=20 to find anything. Is there anything? I know that Mr Hammerling and so many others have worked like slaves on=20 Jalv2. Guys, just give me a few hints. --Bob Axtell --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
