ReverseFind

INTEGER ReverseFind(STRING MATCH_STRING, STRING 

SOURCE_STRING

[, INTEGER START_POSITION]);

Finds the position in SOURCE_STRING where MATCH_STRING last occurs. 

MATCH_STRING is a STRING containing the searched for data. 

SOURCE_STRING is a STRING containing the data to be searched.

START_POSITION is an INTEGER which tells REVERSEFIND at what character 
in the string to start the search, and is 1 based. If it is not specified, it defaults to the 
end of the string. 

The index of where MATCH_STRING last occurs (going right to left) in 
SOURCE_STRING. If the data can not be found, or POSITION exceeds the length 
of the SOURCE_STRING then 0 is returned. The index is 1 based.

STRING_INPUT IN$[100];

INTEGER START_LOC;

 

CHANGE IN$

{

START_LOC = REVERSEFIND(“XYZ”,IN$);

PRINT(“last XYZ occurance was found at position %d in %s\n”, 

START_LOC,IN$);

}

If IN$ was set equal to “Hello, World!” then START_LOC would be 0 since “XYZ” 
can not be found. If IN$ was equal to “CPE1704XYZXYZ”, then START_LOC 
would be equal to 11.
