Slowing Things Down On VIC, 64, Or PET/CBM

I found something very interesting while experimenting with my 64. While listing a program, I noticed that if you press the CTRL key the listing will slow down. Does this work on all Commodore computers? Is it supposed to do this?

Yes, it is. Pressing the CTRL key on the Commodore 64 or the VIC-20 will slow the listings, and some BASIC programs. On the older CBM (Commodore Business Machines) computers like the 8032, the PET, etc., pressing the 1 key will do the same thing. This is to allow you to read the listings more easily as they scroll by.

To see how this affects a BASIC program, type, enter, and RUN the following program. While it is running, press the CTRL key and see what happens:

10 PRINT"A" : GOTO 10
