SL2: Target string to be replaced
SL1: Replacement text that takes the place of target

targ: the text which will end up being replaced in the source string
new: the replacement text for each target encountered
len: the length of the target text (not the length of the source text)

The stack arguments, SL1 through SL3, don't correspond with the local variables targ, new, and len.
I think my problem is that I don't know, or are confused by, what should be on the stack to make REPLS work. I executed REPLS, and the program didn't remove the line feed character from the first extracted string. Also, the program ended up in an infinite loop.

To expand a bit on David's comments:

SL1 means Stack Level 1 - this should be the new text to replace the target string

SL2 means Stack Level 2 - this should be the text which is to be replaced

SL3 means Stack Level 3 - this should be the original string

In order to replace a line feed in the original string, use 10 (the ASCII code for LF) for SL2.
