Thanks for your suggestion, which worked.

To answer your questions, the character you get for a given CHR() value can depend on the font. In my case I was using Courier New.

I have a small program which displays the characters and their ASCII codes one at a time on the main screen for any font, which you may find useful:

cTest_font= GETFONT()
MODI WINDOW SCREEN NOCLOSE FONT LEFT(cTest_font,AT(",",cTest_font)-1)
CLEAR
FOR nCycle = 0 TO 255
    cResult = CHR(nCycle)
    ? STR(nCycle,3) + " " + cResult
    IF MOD(nCycle,20) = 0
        WAIT WINDOW
    ENDIF
ENDFOR
RETURN
