to specify the dots in one vertical column of dots, the LQ expects dl x 3 bytes of data to follow d2. An example character definition program should make this clear: 10 LPRINT CHR$(27)"x0" 20 LPRINT CHR$(27)"&"CHR$(0); 30 LPRINT "@@"; 40 LPRINT CHR$(1)CHR$(9)CHR$(l); 50 FOR I=1 TO 27 60 READ A: LPRINT CHR$(A); 70 NEXT I 80 LPRINT "@@@@@" 90 LPRINT CHR$(27)"%"CHR$(l); 100 LPRINT "@@@@@" 110 LPRINT CHR$(27)"%"CHR$(0); 120 LPRINT "@@@@@" 130 END 140 DATA 1,0,0,2,0,0,4,0,0 150 DATA 8,0,0,23,255,240,8,0,0 160 DATA 4,0,0,2,0,0,1,0,0 In line 10, the ESCape "x" command selects draft style printing.
