1 | /* |
2 | * This program scans a file which describes a keyboard. The output | |
3 | * of the program is a series of 'C' declarations which describe a | |
4 | * mapping between (scancode, shiftstate, altstate) and 3270 functions, | |
5 | * characters, and AIDs. | |
6 | * | |
7 | * The format of the input file is as follows: | |
8 | * | |
9 | * keynumber [ scancode [ unshifted [ shifted [ alted [ shiftalted ] ] ] ] ] | |
10 | * | |
11 | * keynumber is in decimal, and starts in column 1. | |
12 | * scancode is hexadecimal. | |
13 | * unshifted, etc. - these are either a single ascii character, | |
14 | * or the name of a function or an AID-generating key. | |
15 | * | |
16 | * all fields are separated by a single space. | |
