Rick...
The period and dollar sign are called meta-characters. They allow really
cool stuff to happen using regex, but to treat them as "themselves" you have
to escape them with a backslash.
The period matches ANY one character.
The dollar sign anchors a match at the end of a string.
string = abc
REReplace (string , ".$", "", "all")
would replace "c"
I'll go a little further and say these other meta-characters are also VERY
useful.
[] = a character "set".
[0-9] = any number
[a-z] = any lowercase letter
[abc123] = the letters a,b,c and the numbers 1,2,3
* = as many as are there.
.* would replace EVERY character in a string
+ = matches one or more characters
string = abc123
REReplace (string , ".+", "", "all")
replaces the entire string
? = matches 0 or 1
string = abc123
REReplace (string , "[0-9]?$", "", "all") | replaces 3
^ = anchors at the beginning of a string
REReplace (string , "^[0-9]$", "", "all") | replaces nothing

Thanks, Claude...that seems to have done just what I needed.
What do the \'s do? And the + sign?
