REVERSEFIND
Name:
ReverseFind
Syntax:
INTEGER ReverseFind(STRING MATCH_STRING, STRING
SOURCE_STRING
[, INTEGER START_POSITION]);
Description:
Finds the position in SOURCE_STRING where MATCH_STRING last occurs.
Parameters:
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.
Return Value:
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.
Example:
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.
