I want to make an alias. And I need to check if there are any arguments. Im pretty sure I once did this buy typing this:
#alias test {#IF (%1 == {} ) {do this} {do %1}}

But it doesnt seem to be working, was any thing changed in the newer ver?

Well, this works, at least on a test alias I made.

#alias test {#if (%1) {do %1} {do this}}

You can also use the %testparam() function if you need to know how many arguments there are.

The function is named %numparam. (testparam is an alias used in the example in the help file for %numparam.)

#IF %numparam {do %1} {do default}

I've also used the %null function to perform this test.

#IF %null(%1) {do default} {do %1}

This will work, as well.

#alias #if (%len(%-1) > 0) {do true stuff} {do false stuff}

However, I like the %numparam better.
