C.10. - psych.4
Psych.4 generates a random psychedelic pattern.
fn psych.4 fn psych.4 arg fn psych.4 par1 par2 or fn . [arg or par1 par2]The patterns psych.4 generates are determined by two numbers. You can select the numbers or you can let the computer select random values. If you invoke psych.4 with no arguments, you will be asked if you want it to use random numbers. Whenever you give two numerical arguments, those values are used to create the pattern. A single numerical argument
arg
makes the function use random
numbers for subsequent invocations.
When the program is selecting random numbers, values for
par1
are between 0 and 10, and values for
par2
are between 0 and
20.
