Re: [ql-users] Lynx
Hi, I am using lynx to view edit local HTML files. Thanks for the responses I have now solved my problem, basically the fork program that converts unix names to qdos is not found by lynx unless it is on the qdos default program device. There does not seem to be a system variable to set for this. Phoebos wrote 2 articles for QToday about internet access from the various ql systems he has promised to place the software he discussed on his website. Duncan Those articles from Phoebus are also available on my QL Documentation CD. Unfortunately, I think they've been added since the version that was released as a QL Today cover CD. If Phoebus is happy for me to do so, I could add his articles to my website. Also on my website is a copy of Lynx runtime (i.e. without the sources etc) to get people going until they are confident enough to set it up to their own requirements. I've successfully used it get online from recent versions of QPC2 with TCP/IP access capabilities. Writing a browser for QL systems is probably too ambitious a job, although that said Tarquin did write a HyperBrowser some time ago. IIRC that was a html to text converter which also let you click on links to go from page to page or to view images via Photon. -- Dilwyn Jones -- No virus found in this outgoing message.

[ql-users] Easel graphics
Based on feedback received about my BMP program so far, can anyone help me with information about Easel graphics? Easel has a screen dump facility and can generate saved pictures using the PRINT command, option S for save image to file and the file generated seems to depend on what filename extension you give it: PIC or SCR seems to generate a 32K screen file CUT seems to generate a pointer environment area save file 10 bytes longer than a screen file (that is, a screen with a 10 byte header at the start of the file). It only seems to work in mode 4 though. If I save a CUT in mode 32 on QPC2 from Xchange Easel it seems to generate a header of a mode 32 file, but then proceeds to put a mode 4 picture after it, which confuses graphics programs because they see the header, try to load it as a mode 32 and it all goes belly up. I'm not sure if I'm going about this correctly since I've never really tried saving Easel graphics before! So, what (if anything) am I doing wrong, or is just that Easel doesn't really know how to handle correctly anything other than mode 4 and mode 8? -- Dilwyn Jones -- No virus found in this outgoing message.

However, as it does not recognise mode 32, it still stores a mode 4 file. I am surprised it manages to handle mode 8 to tell you the truth, as does it not only support the 4 colours anyway?? Actually, I didn't check that. I think you're right, it only does mode 4. As far as I can see it seems to send the current mode number to file, then saves 32768 bytes of graphics. BTW, these CUT files are only available in Xchange Easel, not standard QL Easel. Having just spent half an hour tinkering with these, I think I understand what's going on now. It's not too difficult to detect and trap: IF mode_byte=16 THEN IF file_length=32778 THEN mode_byte=0 : REMark handle as mode 4 END IF -- Dilwyn Jones -- No virus found in this outgoing message.

As far as I can see: uti_usemenus uti_hotstuff uti_usethings uti_thingjump uti_thingvector That should be all. That's useful Regarding the issues: 1. In uti_pulldown_long_asm the instruction xjmp appears. This is almost certainly a macro and I would expect it to be in mac_xref. It is not there. Yes, that was Jochen's addition. xjmpmacro name xref[name] jmp [name] endm That was my guess xjsr works likewise. 2. The file uti_explanation_asm asks for mac_menu_long to be included. Even I had to dig to come up with that file. It's indeed just a version of mac_menu with some minor alternation to have long relative pointers. I can provide it to you if you want. Thanks very much for the offer. However Jochen offered these some time ago when I was writing TurboPTR and CPTR. I found a way of ensuring that there would always be enough free space within a word of the source so that the long word approach was not needed.

Re: [ql-users] Easel graphics
IF mode_byte=16 THEN IF file_length=32778 THEN mode_byte=0 : REMark handle as mode 4 END IF Now now Dilwyn, not so fast !! 1) You cannot presume that if the file length is 32768 that it is mode 4 (you are forgetting about the header in the file length btw - so should be testing 32778). Also, as it is a cut area, it is possible that another program could provide an area which actually is in mode 32 and just happens to be 32768 (or 32778) bytes OK then, if mode_byte 8 and width=512 and height=256 and filelength=(10+32768) then mode_byte=0 2) Now that Xchange can work with bigger screens - can it actually display Easel in more than 256x256 pixels and save the larger screen area?? Yes, it can display more screen area, no it can't save it. You get the top 32K as far as I can tell. Certainly, it remains a 32K file with bottom of the graph missing. If you are in a mode 4 hires screen, xchange 3.90L seems to cope (but not in anything other than mode 4). If in high colour modes, the graphs don't always display correctly, sometimes not at all. Marcel's hacked version seems to work in mode 32 at least, though I haven't tried all the possible graph variations. I should have mentioned that only Xchange Easel can save the CUT file format. Standard QL Easel can only save ordinary 32K screens. -- Dilwyn Jones -- No virus found in this outgoing message. Checked by AVG Free Edition.

Yes, I didn't change that part of the code. It's possible to do, but oh well, one could also just use any other screenshot utility to do so. If anybody wants it badly enough to sponsor the development we can talk again, but I don't suppose that is the case ;-) If in high colour modes, the graphs don't always display correctly, sometimes not at all. Marcel's hacked version seems to work in mode 32 at least, though I haven't tried all the possible graph variations. As per documentation, pies don't work, the rest is flawless as far as I know. I should have mentioned that only Xchange Easel can save the CUT file format. Standard QL Easel can only save ordinary 32K screens. That is because this was not done by Psion but by Erling.
