I use mirc 6.17 and with this version I have the following problem:
on *:input:*: {
set -n %origtext $1-
..etcetera..
I thought the -n switch would prevent $1- from being evaluated, but when I enter 8 - 1 the answer 7 is placed into %origtext. When I enter 8-1 indeed 8-1 is placed into %origtext.
What is wrong?
