| Action: |
Return a substring of the target string argument. The returned substring characters begin with the start character position (1-based) and continue for len characters. If no len value is specified, the returned substring extends to the end of string. Syntax: &&substring(string,start[,len]) where the arguments observe the rules for &&function string arguments. For example, the first &&substring call in the following fragment returns b; the second returns bc; the last returns c: &&substring('abc',2,1) &&substring('abc',2) &&substring('abc',3) |
