27 | DESCRIPTION | |
28 | ||
29 | This module supports reading of VERSAdos relocateable | |
30 | object files. | |
31 | ||
32 | A VERSAdos file looks like contains | |
33 | ||
34 | o Indentification Record | |
35 | o External Symbol Definition Record | |
36 | o Object Text Recrod | |
37 | o End Record | |
