Font height / width control in PB DOS?

[Robert E. Carneal]

Is there any way to display to the screen in a readable?

I would appreciate being able to use double wide, double high
characters to get the user's attention. Has anyone done this,
and made it work with a NEC monitor?

Sometimes I come across a need to display more than 90
characters in a row. Rare, thank goodness, but can the opposite
of the first question be done? Make the characters temporarily
smaller? 110 CPL would be nice.

Thank you.

the simplest way I've found is:

WIDTH 40

this will produce a slightly larger and more readable font.

You can also use the vesa modes, if your card supports them(most do).
modes 109 thru 10C support 132 columns of text. A little hard to get
started but probably worth the effort. I have some code for using the
vesa modes here
but there is nothing on how to print in text mode. you might try
something like this:

'****************************************************************************
SUB TTYPrint(Letter AS STRING)
DIM I AS STATIC INTEGER
DIM TX AS STATIC BYTE
DIM Clr AS STATIC BYTE
   Clr = 7 'vScrnTxtFG
   FOR I = 1 TO LEN(Letter)
      TX? = ASCII(MID$(Letter, I, 1))
      REG %AX, (&H0E00 + TX?)
      REG %BX, (&H0000 + Clr)
      CALL INTERRUPT &H10
   NEXT I
END SUB

'****************************************************************************
SUB TTYLocate(Row AS BYTE, Col AS BYTE)
DIM TX AS STATIC WORD
   REG %AX, &H0200
   REG %BX, &H0000
   TX?? = Row
   ROTATE RIGHT TX??, 8
   REG %DX, (TX??+Col)
   CALL INTERRUPT &H10
END SUB

You can probably do much better. I havn't messed with text modes
very much. there is also some crude font stuff in there as well
don't know if that will help or not?
