Testing the correction

Programming Tools Guide
Chapter 1, Using programming tools

The program testcase should be retested to ensure the corrected pointer causes the correct behavior.

   testcase
   this is a test of the testcase program
   this
   is
   a
   test
   of
   the
   testcase
   program

With no character argument specified, testcase responds with one word per line. This is the correct behavior.

   testcase -t
   this is a test of the testcase program
   this 
   test
   the
   testcase

In this example, with the -t as an argument, testcase has printed out, one word per line, only words with the letter t. This is the correct behavior. The assumption that the pointer was incrementing regardless of whether or not a match condition existed was correct. Changing it solved the problem within testcase.
