Can anyone tell me how to set an IF command in an alias, so that if %4 is a certain word, if performs a set action, and if not, ignores it an moves on.
I've tried

Perhaps, #if %word( "porcupine", %4) {get porcupine} help there.

Edit: Hrm, I didn't read it fully. You would need to store the fourth line somehow. I don't know how that would be done, without more understanding of what occurs before porcupine.

%4 is the fourth word in the input command. ie:
ALIASNAME %1 %2 %3 %4

so you shouldnt need to store the command. it seems to remember it for the duration of the alias' running.

#ONINPUT {^(*)$} {#IF (%4 = "porcupine") {get porcupine}}

Doesnt work. just catches the alias into an eternal loop where it continually tries to pick up a body

if that was a copy and paste this woulda been simpler if anyone noticed that:
1) Fergal1982 said if and not #if
and
2) Fergal1982 said }{} not } {} (Fergal1982 missed a space)

This works for me

#IF (%4 = porcupine) {get porcupine} {}

Ok, just one more thing. Often %4 isnt filled out at all (most of the time only %1 is filled out), now when i run the script, it keeps running the commands (get porcupine, etc) that ive put in as above.

Its not affecting the functioning of the script, but it looks untidy, is there any way to stop it doing that?

Thanks

Well, id really need to see the whole body of this to be sure, but you could use nested ifs to take care of this situation. As follows:

#IF (%4 = '') {} {#IF (%4 = porcupine) {get porcupine}}

You should always use quotes around strings. Here is what is happening when %4 is empty

#IF ( = Porcupine) {get porcupine}
Since there is nothing to evaluate on the left side it again becomes this,
#IF (Porcupine) {get porcupine}
Which will always be true.

This is what you want,
#IF ("%4" = "Porcupine") {Get Porcupine}

Missed the "'s around Porcupine but never thought about for the %4
