[REBOL] Re: Comparing pairs
From: dada:gecko:verizon at: 23-Jun-2002 20:53
From the manual:
Do not enclose conditional expressions in a block. Conditional
expressions enclosed in blocks, always return a true result:
if [false] [print "yep"]
yep
so, if I do this:
if hero/offset == treasure/offset [
alert "You found the treasure!"
show treasure
]
everything works fine.
