Hi all,

Some time ago, I wrote the following BASIC program for another YouTuber so he could demonstrate the Beeb's character set in each of the seven screen modes.
Code:
10 FOR M=0 TO 7
20 MODE M
30 PRINT "Screen mode "TAB(0,-1);(M):PRINT
40 FOR C=33 TO 255
50 REM *****************************
60 REM Following line prevents the
70 REM output of non-visible control
80 REM codes in modes 0 to 6
90 REM *****************************
100 IF M<>7 FOR C=33 TO 128
110 PRINT TAB(0,-1);(C)"=";CHR$(C);" ";
120 NEXT C
130 IF M=7 GOTO 170
140 PRINT:PRINT:PRINT "Press any key . . ."
150 KEY% = GET
160 NEXT M
170 IF M<>7 MODE 7
180 PRINT:PRINT:PRINT "All modes have now been displayed."
190 END
Hope you find it useful.

Cheers,
