Subject: many characters on a screen
 
Hi,
 
Someone lately wrote he wanted to print many columns on a screen.
Since Powerbasic does not have a standard function to do this, Other
solutions must be found. The only way I know is to call a VESA function
through interrupt &h10
 
here's the source :
 
reg 1, &h4f02
reg 2, XXXX
call interrupt (&h10)
def seg = &hb800
poke$ 0,"H e l l o   W o r l d "
def seg
end
 
XXXX in this program must be substituted by one of the folowing numbers :
XXXX          resolution
108h          80x60 text
109h          132x25 text
10Ah          132x43 text
10Bh          132x50 text
10Ch          132x60 text
 
there are a few minor troubles though. First of all : not all video cards
allow you to use vesa modes. The second problem is that the Powerbasic
compiler doesn't know we changed the resolution of the screen, so even a
simple print probably won't work.
 
Whoever asked for it : good luck.
 
Wiebe.
