[ql-users] Bug in GWASL (I think)
I am testing out some code in QLTDIS which was assembled with George Gwilt's GWASL assembler version 1.2. So far so good. In testing MOVE An,USP and MOVE USP,An I find that GWASL assembles as follows : MOVE USP,A7 = $456F = 0100 0110 0110 MOVE A7,USP = $4E67 = 0100 1110 0110 0111 I had a few problems tracking this down because QLTDIS failed to disassemble and gave me a DC.W $456F. The problem is present for every register number, not just A7. I've tested it ! My docs say that bit 3 determines the direction (to or from USP) but George is setting/changing bit 11 as well. Are my docs wrong - I have the opcode as $4E6x where x = direction in bit 3 and the address register number in bits 0 to 2. (If I am right and this is a bug, has anyone got Georges Email address please. Thanks.) Norman.

RE: [ql-users] Bug in GWASL (I think)
Sorry folks, can't convert hex to binary ! I meant to type : MOVE USP,A7 = $456F = 0100 0101 0110 and not as I originally had it ($5 = 0101 and not 0110 !) Also the stuff about bit 11 is nonsence. I meant to write (oh yeah ?) that the second nibble should be $E instead of $5. It's been one of those days ! Norman.

I've found George's email address in the readme for the turbo qptr toolkit. Norman. Norman Dunbar EMail: [EMAIL PROTECTED] Database/Unix administrator Phone: 0113 289 6265 Lynx Financial Systems Ltd. Fax:0113 201 7265 URL:http://www.LynxFinancialSystems.com
