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