 * function to find a chosen string in the index key file (just do a
 * binary search to locate it):
 *
 *  ("LOCATE", targetString, keyFileRefNum)
 *  --  returns wordNum for the targetString if it is found in the
 *      key file; otherwise returns wordNum for the word alphabetically
 *      preceding targetString followed by "{targetString not found!}"
 *      on the second line of the answer...
 *
 * function to create a new subset:
 *
 *  ("NEWSUBSET", textFileRefNum)
 *  --  returns subsetHandle for a new subset that it creates, big
 *      enough to do subset browsing -- but does NOT initialize that
 *      subset or check to see whether another subset already
 *      exists.  Beeps and gives error msg if it fails...
