newRPL: Adding string processing commands?

[Vtile]

Linecount - Counts lines of text object
Wordcount - Counts words of text object ( separator as char )
ExtractWord - Extract the N-th word out of a string. ( separator as char )
WordPosition - Search position of Nth word in a string.
StrTrimSet - Remove any leading or trailing characters in a set from a string and returns the result

??? I must admit that I'm not fully aware of the capabilities of the uRPL set of commands and what can and can not be done to strings with them. Also some of these could be just a overloaded functionality of the list commands like POS, SIZE, GET, PUT

Above commands are mainly from FPC RTL http://www.freepascal.org/docs-html/rtl/...dex-5.html
