I need to compare single characters from a variable against single characters in a string list to see if they match.

For example if I have a variable set to "abc" and a string list, the first entry of which is "bcd" can I compare them and see if the first letter in the variable (being 'a') is the same as the first letter of the first entry in the string list (being 'b'). Also is the first letter in the variable equal to the second letter of the first entry in the string list, and so on.

Ideally I want to just use a #FORALL to compare the variable to every entry in the string list.

I know my way around cmud fairly well, just a kick in the right direction or a suggestion or anything would be great. Thanks

1)some combination of %left(), %right(), %leftback(), and %rightback() to pull out the desired substring

2)%begins() to test against the beginning of a string

3)see #1 for testing against 2nd/etc letter of each element in the stringlist

Also don't forget about %copy().

That should work. Seems a bit sloppy combining %right and %left to reach the middle letter, but should work anyways.
Thanks!

Edit: %copy works perfectly. Thank you.
