HiSoft Basic 2.10 ================= UPDATE version 2.0 ================== I've now tested all the RGB/TV resolutions. See the extra table. FALCON SCREEN RESOLUTIONS ========================= One major problem I had when making my programs was detecting which damn screen resolution the user was loading my programs in. Could they be in a weird True Colour resolution? If they have a VGA do they have the Double Line On or Off ? All these questions and no obvious answer made me fiddle around and here is what I found... SYSTAB & GETREZ% ================ Both these calls are supposed to be used independantly, but with the amount of resolutions on the Falcon it makes sense to combine their results to find out the correct resolution and warn the user accordingly. r%=peekw(systab) g%=getrez% The above are the methods used from within HB. You will need to have the Xbios library installed for the getrez command to work or else it will return a value of 0 each time regardless. RESULTS for a VGA ================= Falcon Resolution SYSTAB GETREZ ------------------------------------------------- 4 colour, 40 column, DL Off 2 7 4 colour, 80 column, DL Off 2 2 4 colour, 40 column, DL On 2 0 4 colour, 80 column, DL On 2 1 16 colour, 40 column, DL Off 4 7 16 colour, 80 column, DL Off 4 2 16 colour, 40 column, DL On 4 0 16 colour, 80 column, DL On 4 1 256 colour, 40 column, DL Off 8 7 256 colour, 80 column, DL Off 8 2 256 colour, 40 column, DL On 8 0 256 colour, 80 column, DL On 8 1 True Colour, 40 column, DL Off 16 7 True Colour, 40 column, DL On 16 0 ST LOW 4 0 ST MED 2 1 ST HIGH 1 2 RESULTS for an RGB ================== Falcon resolution SYSTAB GETREZ ------------------------------------------------- 2 Colour, 80 column, Int Off 1 1 2 Colour, 80 column, Int On 1 2 4 Colour, 40 column, Int Off 2 0 4 Colour, 40 column, Int On 2 7 4 Colour, 80 column, Int Off 2 1 4 Colour, 80 column, Int On 2 2 16 Colour, 40 column, Int Off 4 0 16 Colour, 40 column, Int On 4 7 16 Colour, 80 column, Int Off 4 1 16 Colour, 80 column, Int On 4 2 256 Colour, 40 column, Int Off 8 0 256 Colour, 40 column, Int On 8 7 256 Colour, 80 column, Int Off 8 1 256 Colour, 80 column, Int On 8 2 True Colour, 40 column, Int Off 16 0 True Colour, 40 column, Int On 16 7 True Colour, 80 column, Int Off 16 1 True Colour, 80 column, Int On 16 2 THAT'S IT! ========== I am sure you can see from the above table that when you check the systab and getrez results if they equal 16 and 7 then the user is in the True Colour, 40 column, Double Line Off mode... and so on... PROBLEM ======= There is only one problem though. The ST LOW results (4/0) are the same as the 16 colour, 40 column, Double Line On (4,0). This is because essentially they are the same screen dimensions but you still might like to know which one of the two it is. Well I can't help you here I am afraid but if anyone out there can then PLEASE get in touch! >>> Another problem is that there is no way to detect which type of monitor the user has. The RGB and VGA results are pretty much the same in most respecst, therefore you have problems, especially as although the systab and getrez results are the same, the display area available most certainly is not <<< CONTACT ======= Falcon owning, HiSoft Basic programming people please get in touch with me to swap ideas and routines.
