Description
This function searches for the first occurrence of searchString$ or searchContainer$$ within targetString$ or targetContainer$$, starting at character position startPos. (If startPos is less than 1, it's treated as 1.) If a match is found, the function returns the character position (1..255) within targetString$ or targetContainer$$ where the match begins. If no match is found, the function returns zero. The string search is case-sensitive. Note: INSTR always returns zero in these cases:

* when startPos is greater than LEN(targetString$) * when LEN(searchString$) is zero.
