Hi

I disassembled the Pointers users toolkit with Disa and reassembled the code, with Qmac.

On loading I to QPC2 running v3.41 the code seems to corrupt the operating system. The new Extras command displays the added procedures and function in columns. But there seems to be screen corruption.

But when loaded into sQLux running Minvera all works fine.

The toolkit was written when Qram was the main Qjump Window g system, would there be any difference between the way Qram and the Extended Environment works?

Do you mean that just the reassembled code causes problems in QPC2, or that the original code also causes the same problems?

If it's just the reassembled code, I would do a byte by byte comparison with the original to find any differences.

sorry for not being clear, the disassembly output from DISA is what I meant.

I will do as you advise and compare the compiled binary file with the original.

Bug it does seem strange that all works okay in Minerva. The problems come in SMSQ/E v3.41 in QPC2, SMSQmulator.

I am sure that Jochen would use Qmac, just have understand the assembler code... more long haired books to read!

Jochen always used the GST Macro Assembler, perhaps later the Qmac/Qlink.

that what I thought, it is is the same setup that I use.

I will have a better look at this and see if I can understand the code.

Hi Derek,
Haven’t followed these posts but if this Is about being able to understand and get engaged with the pointer environment,
especially if it expands usable SBASIC commands I’m interested.

As you know not so hot on assembly!
