Mail - Print Line 32-character font.

 Print line 32-character font.

 Lower byte character generator should be
empty.
 How to print the symbol directly
integrated in-line printing for maximum speed. Using
Print a character of any entry point
procedure body printing line rather
difficult.

hl-address of the start line
b - length of string = 32 always. Stops
print on reaching # 0D or limit
string length.
c-position Y.

Position X = 0 is rigidly defined, although it is possible
no difficulty in reading the address from the table
add the necessary X. After such a modification is possible to 
print a single character with any coordinates, assuming b = 1. 
The proposal was not made by me, because procedure was 
developed exclusively Print with 0-position to X.
