THIS LINE SPACING IS SET TO l/6 INCH.

Line 40 defines and changes the line spacing. The command (ESC)“A”CHR$(n) defines the line spacing as n/60 of an inch; the (ESC)“2” command changes the line spacing to the amount defined by the previous (ESC)“A”. The loop that is started in line 20 increases the value of n (the variable I in the program) each time it is executed. So the line spacing increases as the pro- gram continues. Line 30 shortcuts the loop when I = 13, since BASIC won’t let us send CHR$(l3) without adding an unwanted CHR$(lO) to it. Finally, the (ESC)“A”CHR$(lO) and (ESC)“2” commands in line 80 reset the line spacing to 6 lines per inch (IO/60 or l/6 inch).

NOTE: When you look the results closely, the line spacing with the (ESC) “A” CHR$(l2) command sets the line spacing to l/6 inch instead of setting 12/60 inch. This is because that the g-pin printers are normally sets the line spacing to 12/72 inch (l/6 inch) with this command, and most software programs use this command to set the line spacing to l/6 inch, and we’ve thought the compatibility with those programs. (The same reason for the (ESC) “3” CHR$(36) command.)
