Using Preview-80 With 64 SpeedCalc
I own a Commodore 64 and look forward to getting new programs from COMPUTE! each month, especially utilities. After typing in SpeedCalc (COMPUTE!, January 1985), I was pleased to find that the "Preview-80" program (COMPUTE!'s GAZETTE, November 1985) works just as well with SpeedCalc as it does with SpeedScript. This lets you preview a SpeedCalc file in 80-column format on the screen before printing it out. The procedure for using Preview-80 is the same as usual. First, load Preview80 with LOAD"PREVIEW80",8,1. Then type NEW, and load SpeedCalc as you would normally. Instead of typing RUN to start SpeedCalc, type SYS52000 and press RETURN. SpeedCalc will become active as usual. But when you press SHIFT-CTRL-P for printed output, and then press S for output to the screen, Preview-80 takes over. All of the Preview-80 options are available; to exit the Preview-80 window, press RUN/STOP twice.
Thanks for the tip.
