I just give a try using Daniele Terdina's Q-Emulator where the SuperBasic program gived on my previous Email works properly.
So I have now my answer : QL2K need to be modified to support second screen. Thanks Tony, Jimmy. -----Message d'origine----- De : [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] De la part de QL2K Envoyé : dimanche 27 avril 2008 14:59 À : [EMAIL PROTECTED] Objet : Re: [Ql-Users] Need some information on Dual Screen and Minerva ROM. Ok, my head hurt ;-) This modes are only usuable by JOBS ? Or can I test something with superbasic too ? What I try is something like this : 10 MODE 16650,-1 (This goes to a full black screen) 15 OPEN #3,SCR_512x256a0x0 (Try to open a full screen windows on second screen) 16 INK #3,7 (Force ink just in case) 17 PRINT #3, "Hello" 20 A$=INKEY$(-1) 30 MODE 112,-1 With this, just before typing a key I just got a full black screen. Does I have to made a try with poking after &h28000 ?

The original one-parameter call is exactly as before. The new form is: MODE screen_mode,display type Screen mode accepts the normal 4, 8, etc, but with a few additions (see below). Display_type is simple, 0 for monitor, I for 625-line TV, and 2 for 525-line TV, or (usually) -ito leave the display type alone. Very little software uses the display type record, as old versions of SuperBASIC smashed it! Screen_mode is very complex... The two screens are known as ScreenO and Screeni. Each screen may be in 4-colour mode or 8-colour mode, or blank. Each job now has a "default" screen on which any new windows will be opened - it can change this default to have windows open in both screens. The screen which is not the default for the current job (the one calling the new MODE) is the "other" screen. Note that is is not necessarily the case that the defaUlt screen for a job is the same one the user is looking at (the displayed" screen). Oh, and the user can’t necessarily see the displayed screen, it might be blank. Your head hurt yet? Toggling: MODE 64+n, -1 toggles various attributes of the display, where: n Toggles... 1 other screen from visible to blank 2 default screen from visible to blank 4 other screen from 4-colour to 8-colour 8 default screen from 4-colour to 8-colour 16 displayed screen from Screen0 to Screeni 32 default screen from Screen0 to Screeni You can add together the various values for n to combine effects, so n=12=8+4 will toggle the colour modes of both screens. Note: a change to the default screen takes place before any of the others. Also, none of these calls do the “forced re-draw” imposed by the one-parameter version of the MODE call. Setting: MODE -16384+128+k*n+c, -1 sets or resets display attributes. The values of n are as above. k Sets... o ... to the “from” column above 1 ... to the “to” column above 257 toggles, as above Values of k can’t be combined. The c portion controls which screen is force re-drawn: c Re-draws... -16384 other screen 32768 default screen You can add the c values to re-draw both screens. So... MODE 80, -1 toggles the “displayed” screen (80=64+16) MODE 96, -1 makes subsequent VPENs happen on what was the “other” screen (96=64+32) MODE 112 ,-1. does both the above simultaneously (112=64+32+16) MODE 16560,-1 sets default to Screeni, displays it in 4-colour mode, and force re-draws all windows in it (16560=16384+128+1 (32+1 6)+32768) Tony -- QBBS (QL fido BBS 2:257/67) +44(0)1442-828255 [EMAIL PROTECTED] http://firshman.co.uk Voice: +44(0)1442-828254 Fax: +44(0)1442-828255 Skype: tonyfirshman TF Services, 29 Longfield Road, TRING, Herts, HP23 4DG _______________________________________________ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm _______________________________________________ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm _______________________________________________ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm
