Howtheprogram works
This program begins by assigning a number of printer commands to
BASIC string variables (lines 1000to 1090).Youcan find most ofthese
commands near the beginning ofAppendix B.
The WIDTH “LPT1:” 255 statement in line lllOmeansintinite line
width. It prevents the IBM-PC from inserting unwanted carriage returns
and line feedsin graphics data.
Actual printing beginsin line 1120.Using the preassignedcommands,
the program prints samples of its different type styles, including a line
showing all stylesin italics, followed by samples of the print pitches, then
some double and quadruple-sizedprinting.
Next comes the central attraction oftheprogram: aline oftext printed
twenty times in expanding and contracting loops to give a barrel effect.
Thework isdone by four printer commands: acommand setting the right
margin (line 1400);a centering command (line 1420);acommand to vary
the line spacing(lines 1440and1490); and acommand to micro-adjust the
space between characters (lines 1450and 1500).
