As you can see, when the big character command is used, the baseline for each character does not align. If you want to align the baseline, try this program:

10 ’ Demo of aligning BIG characters

20 LPRINT "THIS IS rr;

30 LPRINT CHR$(27);"j";CHR$(21);

40 LPRINT CBR$(27);"h";CHR$(l);

50 LPRINT "DOUBLE";

60 LPRINT CHR$(27);"h";CHR$(O);

70 LPRINT CHR$(27);"J";CHR$(lB);

80 LPRINT " SIZED PRINTING."

90 LPRINT :LPRINT :LPRINT

100 LPRINT "THIS IS 'I;

110 LPRINT CHR$(27);"j";CHR$(63>;

120 LPRINT CHR$(27);"h";CHR$(2).

,

130 LPRINT "QUAD";

140 LPRINT CHR$(27);"h";CHR$(O);

150 LPRINT CHR$(27);"J";CHR$(63);

160 LPRINT " SIZED PRINTING." :LPRINT :LPRINT

When you run this program, you will get this:

nThe macro control code

The last of our group of miscellaneous codes is definitely not the least. It is a user-definedcontrol code, called a macro control code. The term macro is from the jargonese macro-instructionwhich refers to an instruction that “calls,” or uses a group of nor- mal instructions. In computer programming macro-instructions (which are similar to subroutines) save programmers a lot of timeand effort. Your printer’s macro can save you a lot of time and effort also.
