Icon+Unicon/Intro: Difference between revisions

These examples initializes sum and adding all the contents of arglist. The first example uses separate statements, the second too but compresses with a ;, the third is a common contraction, and the last is an error.

<lang Icon>sum := 0 # initial and

every sum +:= !arglist do something() # loop in two statements

sum := 0; every sum +:= !arglist do something() # ; splice

every (sum := 0) +:= !arglist do something() # a common contraction

while sum := 0) +:= !arglist do something() # an error</lang>
