Not sure if you know about this, or whether you consider it a bug.

When using /var to assign a value, the evaluation of 1-1 does not take place, but when spaced out, 1 - 1 it seems to automatically perform the calculation.

I was creating a calculator for mIRC, so that all of my calculations would be recorded and could be referenced later, and i encountered this little bug. I worked around it.

Thanks for your bug report. That is indeed how variable assignment has always worked.

Check out the $calc identifier.

For what it is worth: you can prevent this from happening by using either the -n or the (as yet undocumented) -p switch to /var. For example, the following code excerpt:


..will echo "1 - 1". The exact same applies in cases where the input is not literal (e.g. when assigning one variable to another, with such a "formula" as contents).
