Atari Printers 259
Half-line Feed & Reverse Half-Line Feed
The
half-line feed control code causes the paper in the printer to
be advanced by 1/ 12 inch.
These
control codes are very useful when printing subscripts. For
example, the following program line,
100 LPRINT "8";CHR$(27);CHR$(28);"10";
CHR$(27);CHR$(30);"Base Ten"
would output:
8
10
Bas e Ten
Carriage Return
When the carriage
return code is received, the printerwill return
to the left margin, and an automatic line feed will be generated.
For
example, the following pro gram lin e,
100 LPRINT "JOHN";CHR$(13); "WILLIAM"
would generate the following output:
Underlining
JOHN
WILLIAM
The 51 code causes the und e rlinin g of characte rs to begin. When
an SO code is received, the underlining is discontinued . For
example, the following program line,
100 LPRINT CHR$(lS);"UNDERLlNE";CHR$(14);" STOP"
would generate the following output:
UNDERLINE STOP
