n* (Repeat Function n Times)
The n* function repeats the execution of the specified function n times,
where n is an integer. In the following example, the message Hello
will be sent to the printer five times.
Example:
printer: 5*ibwrt "Hello"
The function name can be replaced with the ! function. Thus, if this
example is done the following way, the word Hello will be sent 20
more times, then 10 more times.
Example:
printer:
printer:
20* !
10* !
Notice that the multiplier ( * ) does not become part of the function
name; that is, ibwrt "Hello" is repeated 20 times, not 5* ibwrt
"Hello" .
