regex
Syntax: %regex(s,regular-expression[,var1,var2,...varN,varN+1])
Related: #REGEX, %subregex, %match
test to see if string s matches the given Regular Expression. If it matches, the position of the match in the string is returned (starting with 1). If it doesn't match, zero is returned. The optional VarN arguments contain the names of variables to store any captured subpatterns (subpatterns surrounded by parenthesis). The additional VarN+1 variable name can be specified to hold the length of the matched pattern.
Examples:
#SHOW %regex("Zugg says Hi","(\w+) says (.+)",Name,Message,X)
displays:
1 - and sets the @Name variable to "Zugg", the @Message variable to "Hi" and the @X variable to 12
