> So the REP function looks at the statement it's part of, finds the variable that is being assigned to, and uses that as the starting string (!). It's kind of like a function, only with a weird implied variable that only works in an assignment. As DonHopkins notes, this appears substantially identical to the assign-equals operators which are generally thought of as "easy and convenient" rather than "weird". How is the line of code "a *= 7" meaning "whatever the current value of a is, multiply that by 7 and assign the result to a" weirder than the line 'a$ = REP("123",4,0)' meaning "whatever the current value of a$ is, do a string replacement on it and assign the result to a$"? |
