Re: Themes

It is a rather simple program. It doesnt have all the tests and error checking of a fully fledged commercial offering. Its a "hacker's" tool. The meaning of that error in that place is that no valid _thb file was found. So either a file name was given but the file was wrong (not a 114b THB...

Re: Themes

Thanks for the mention, Dilwyn. In all modesty I should perhaps add that this is a very
minor update to a minor set of utilities! However, interested parties will be able to
follow the bread crumbs to more fulsome information.

Re: Themes

Hi Duncan, Well, sort of: The Wman 15bit RGB colours dont correspond to those of any of the "natural" modes. Since its quite complicated to unravel the Wman codes to convert them into real colours, and since there are no hooks into the internal routines to do those conversions, I find the ...

Re: Themes

While we wait for a more learned explanation, here is my understanding: These are the new Wman colours, as described in the display_txt document in the SMSQ/E sources. They are not of any particular "mode"; they are mode-agnostic codes. You can use the following colour codes in any wman ob...

Re: A programming question

It seems RAM is limited by compatibility with one of the superbasic compilers (Qliberator?) which used the top 3 bits of the address references to store data about the reference. These need to be 'don't care' for decoding (which also makes it 'fun' to write cache management code...), so only bits 2...

Re: A programming question

I suspected the possibility regarding hardware addresses. So let me be more specific: A user RAM request will never, ever return a "negative" address, right? I guess that by the time we see systems sporting 2 gig or more - in about 2029 Jan 19 03:14:08 (or more likely around 2097 Feb 06 06...

A programming question

Can it safely be assumed that a RAM address can never be "negative" in a SMSQ/E system? Ie, that so much of the system relies on the assumption that RAM will never exceed 2GB, that any negative return from some function can be taken to be an error code rather than a valid address..? Asking...

Let's say you want a number between 50 and 100:

RANDOM gives you a number -32768-32767
Am I missing something here? What about RND(50 TO 100)? or RND(-50 TO 50)? RND already does all the hard work for you..

Re: Announcing: The way, QLiberator use the PE

Hi Ralf, Quite enlightening with regards to the Pointer Environment integration into Qliberator. Yes, indeed. All the indications are that there was a close working relationship between Liberation Software and QJump. @ Ralf, Good idea about your enlightenment project. I hope it is a success! BTW, d...

Just remember to change the blades every few thousand feet ;)
