if Suggestion

if Suggestion

[Mark K. Gardner]

Since Byron is beginning work on a new official version of RC, I would
like to make a suggestion about the if statement.

One of the things which attracted me to RC initially was its "more
C-like syntax than csh". However, I find myself wanting to have an
optional else-if clause in the if statement. I realize that there are
other ways of expressing the same control flow, but either they look
very cumbersome to me (nested if statements) or I get lost in
complexity of expressions connected by && and ||. Is it heresy to
suggest that we add an optional else-if to the if statement? I am not
opposed to the keyword "elsif" (as used in several other languages) to
avoid the dangling else problem. (There goes the likeness to C!)

OOPS! (He said as he wipes the egg off of his face.) I guess I had
better avoid posting until I have had a chance to wake up.

IF does indeed work as Erik says. No change necessary.
