Re: SDC/WIN driver and curious RENAME behaviour...

Well... true to form, within hours of reporting the issue, Wolfgang has delivered a fix for me to test - and it works! I can now successfully RENAME files with the WIN driver on SDC. Apparently, there was a little glitch in how the default WIN_USE mapping to MDV had been set in the driver. I underst...

SDC/WIN driver and curious RENAME behaviour...

Hi everyone Thanks to Wolfgang for his work on porting the WIN driver to QDOS and merging with the SDC driver. As a result, I am now able to mount a number of .WIN container files as WIN1_, WIN2_ etc and in the process, ease the transfer of files from QPC to my QL(s). Loving it! One curiosity that I...

Re: TURBO'd app that hangs the QL on termination...

Hello again! An update to this old issue I was facing, and never quite got to the bottom-of... I have just deployed Wolfgang's SDC/Win driver to my Minerva-based QL and, whilst it still remains unclear the cause of the original hanging of my TURBO'd app, the issue has curiously gone away - with no f...

Re: QL Graphics

Whilst Per has moved on to to fry bigger fish :-) I thought I'd close the Mode4/Mode8 'sample-point' conversation... Should anyone find it of any value, the address offsets (integer) for a set of 127x test-points forming a spiral, based on the 32k QL display can be found attached as a .txt file and ...

Re: QL Graphics

Aha! You have it - thanks. So, this description would imply that the very first pixel on a scanline cannot be made to FLASH (as flashing actually begins at the next pixel.) I'll test that on my QL this weekend - had never noticed a 'missing' flashing pixel on the LHS - but then I practically never u...

Re: Sections or includes in GST/Quanta Assembler

Hi Jan! Just one note: if you only have one _asm file, you can use the -NOLINK option on the GST/QMAC assembler and it will generate the _BIN file directly without intermediate _REL file, thus removing the need to use the linker. You still need to use a SECTION directive though as this indicates tha...

Re: QL Graphics

"Devil's spanner polisher" - I love it! Never come across that term before (but fully understand its intent.) And yes, if an extreme end of a scan-line is contiguous FLASH, it must (?) follow that either the first FLASH toggle bit or the last toggle bit would necessarily be dropped. I wond...

Re: QL Graphics

Hi again Per Coming back to your explicit check for '170' in the high-byte of the pixel-word: 420 IF b% = 170 THEN 430 m% = 8: EXIT pos What makes you sure that 4-consecutive pixels with GREEN component set but no FLASH (if Mode 8) or alternatively, 8 pixels with alternate GREEN bits set (Mode 4) sh...
