== sub ==

: This function returns a substring of the target string at specified indices.

Usage:

: <code><nowiki>{{#invoke:</nowiki>String|sub|''target_string''|''start_index''|''end_index''}}</code>

OR

: <code><nowiki>{{#invoke:</nowiki>String|sub|s= ''target_string'' |i= ''start_index'' |j= ''end_index'' }}</code>

Parameters:

; s
: The string to return a subset of
; i
: The first index of the substring to return, defaults to 1.
; j
: The last index of the string to return, defaults to the last character.

The first character of the string is assigned an index of 1.  If either i or j is a negative value, it is interpreted the same as selecting a character by counting from the end of the string.  Hence, a value of -1 is the same as selecting the last character of the string.

If the requested indices are out of range for the given string, an error is reported.
