Returns the position of a given sub-string in a string.


string_pos(substr, str);

Argument Description
substr The substring to look for in the string.
str The string.

Returns: Real


This function will return the character position of an instance of a sub-string within a string, or 0 if it's not found at all. One use for this is for filtering words that may be considered offensive, or for finding the correct place to insert some text into another string.


if string_pos(",", text) != 0
   string_insert(name, text, string_pos(",", text));

The above code searches the string "text" for a comma, and if it finds one it inserts the substring "name" at that position.
