Usage

{{Str find|text|sub_string}}

Returns the position of first appearance of sub_string in text.

• The comparison is case sensitive.
• Returns -1 if sub_string not found
• Character position is 1 based (not 0 based as usual in calculations).
• If sub_string is empty, this routine returns 1. This case will often have to be handled specially.

In the examples, the string to be searched is Abcdefghijklm:

• A; 1
• a; -1
• def; 4
• klm; 11
• zyx; -1
• empty;klm;-1
