  9.        *       Purpose:
  10.        *          This file contains the main calling
  11.        *          routine for a program which
  12.        *          takes two images and pastes them
  13.        *          together side by side or top to bottom
  14.        *          into a new image file.
  15.        *
  16.        *          There are three files: two input files
  17.        *          (file and file2), and one output
  18.        *          file (file3).
  19.        *
  20.        *       External Calls:
  21.        *          gin.c - get_image_name
  22.        *          numcvrt.c - get_integer
  23.        *                      int_convert
