The way I debug BASIC programs is to use a routine called Puse, which causes a pause. DEFine PROCedure Puse LOcal a$(2) OPEN#20,con a$=INKEY$(#20,-1) CLOSE#20 END DEFine By placing this inside the program I can see what's happening. For example 2000 Fling: REMark some procedure 2005 Puse:PRINT "Line 2000":Puse allows me to see if I have gone past line 2000. Pressing any key allows the program to continue (to the next Puse). You can add a PRINT facility to Puse by: DEFine PROCedure(b$) . . PRINT#20,b$ . . END DEFine This works well even inside compiled BASIC programs.
