Task Version Identification

The first executable statement of a program should be to print out a version identification. The following is typical:

c****************************************************************
       program Clean
          .
          .
          .
       character version*(*)
       parameter(version='Clean: version 1.0 26-jan-90')
          .
          .
          .
       call output(version)

This gives a version and the date when the task CLEAN was last modified. Additionally, this version identification should be included in any history generated by the task.
