In my mud the prompt looks something like this...

496h, 528m, 462e, 0p elrx-

At the end of the prompt are a bunch of letters meant to signify that I have some kind of balance or defense (or to tell me when I am prone)

If I make it so that it is caught with ([erlxpk]) I wind up with %1 = elrx

Is there any type of function or any other means of doing something like

IF %1 contains [letter]
Do this

Try the %pos function.

Alright. I've tried it like this

if (%pos(p,%1)=>1) {stand}
but it's not compiling.

Suggestions?

Use the command character. #if, not if.

Pardon me. That was a C/P error. It is '#if', not 'if'.

I've also tried
$temp = %pos(p,%1)
#if ($temp=>1) {stand}

Not sure what you're trying to accomplish with "=>" but if you wanted 'greater than or equal to' you need to type it as ">=" The first one will cause a compilation error.

Blah. Still not working.

This is the trigger:

^%dh, %dm, %de, %dp ([elrxkp])-

This fires correctly and was checked with an echo in the value.

Both #if (%pos(p, %1)>=1) {stand}
and #if (%pos(p, %1)~=0 && %pos(p, %1)~=false) {stand} {}

do NOT work.

This is what it is firing off of:
574h, 642m, 624e, 0p elrxp-

To debug I attempted to check for both p (which IS in the string) and k (which is NOT in the string)
#echo %pos(k, %1)
and
#echo %pos(p, %1)

Both of these Echoed '0'

If you want it to match only when true, you don't need to add the >=1 bit.

I'm not even sure how that regex is matching with that input to be honest. ([elrxkp])- <-- You are matching only a single character followed by a hyphen with this. Change that to ([elrxkp]+)- and see if your code starts doing what you expect.

Ah well that explains that then regarding the pattern. But all those letters won't appear on the prompt all the time, that's just all possible letters. On IRE muds they tell you stuff like if you're prone, have equilibrium, are balanced, etc. From what I can see in that code doesn't it assume that 'elrx' will always be there no matter what? Anyway this is how I would do it with a regex:
