Expects: AX    1301H

BH    video page

BL    video attribute

CX    length of string

DH,DL row,column to start writing

ES:BP address of start of text to write

Returns: (none)

Info: This displays a string of text, using a specified video attribute

and starting at a specified screen location.

It automatically updates the cursor location, leaving it one

column beyond the last character written.

This function treats these characters specially:

CR  (0dH)     cursor to start of same line

LF  (0aH)     cursor to current clm on next lower line

BEL (07H)     beep the speaker

Notice that you must supply both CR+FL to perform a natural

"newline" (that is, to move the cursor to the start of the next

lower line).

Note: This fn requires that you modify BP.  When calling from high-

level languages such as C, be very careful to save and restore

BP, since it is used to keep track of the "stack frame".
