F10_WLCHARATR (AH
=
09H)
This function writes character and attribute bytes at the current cursor location. If the MultiMode
Video Display Adapter is in one of the alphanumeric modes, a page number may be specified. If
the MultiMode Video Display Adapter is in one of the graphics modes, only the character is
written. More than one character and attribute can be stored by placing the number of copies
desired in CX. This function will wrap around both line and screen if too many characters are
specified. Note that this function makes copies of a single character/attribute combination, it
does not print a string. Refer to the Write String function for that operation.
