For example `PRINT SPC(10)` will print 10 space characters. - -Why didn't they allow to print something else than space characters ? It would have been interesting (?) to have the ability to repeat a sequence of any character. - -Maybe like `PRINT REPT("*",10)` would print 10 asterisks. - -But Applesoft does not provide such an instruction. So are we doomed to use `PRINT "**********"`? - -Here's a technique that will allow you to repeat any character, even in `FLASH` and `INVERSE` without using additional 6502 routines. - -## Discovery -Let's see something weird ... -At the Applesoft prompt, type `FLASH`. -Then `PRINT SPC(10)`. You should now see 10 flashing space characters. -Now, press `CTRL-BREAK`. This exits the "flash" mode (do no type `NORMAL` !!). -Type `PRINT SPC(10)` again. And ... - -WOW ! WHAT IS THAT ??
