  49  * This program scans a file which describes a keyboard.  The output
  50  * of the program is a series of 'C' declarations which describe a
  51  * mapping between (scancode, shiftstate, altstate) and 3270 functions,
  52  * characters, and AIDs.
  53  *
  54  * The format of the input file is as follows:
  55  *
  56  * keynumber [ scancode [ unshifted [ shifted [ alted [ shiftalted ] ] ] ] ]
  57  *
  58  * keynumber is in decimal, and starts in column 1.
  59  * scancode is hexadecimal.
  60  * unshifted, etc. - these are either a single ascii character,
  61  *                      or the name of a function or an AID-generating key.
  62  *
  63  * all fields are separated by a single space.
