String operations syntax defining

[pranay001]

Please comment your opinion on the below syntax formats and also add if few other functionalities are required.

String functions:

String length. Syntax: strlen($string$)

Concat string Syntax: concat($a$,$b$)

Substring Syntax: substr($string$,$offset$,$length$)

Toupper case Syntax: toupper($string$)

Tolower case Syntax: tolower($string$)

Is empty? Syntax: isempty($string$)

[navinsubramani]

The above looks good. Please also add the following functionalities,

Anything to string, str($anything$)

String Concatenation, $string1$ + $string2$

[pranay001]

I added all the functions but I would like to check from you whether shall we have str($anything$) function in string operations or as a part of typecast operations

[navinsubramani]

Make sense to add them to a typecast library for now

[navinsubramani]

This is kept in String Operations since there is no typecast library
