// Purpose: This file is really mis-named. At one time it was going to
|
| 8 |
|
|
// be header file for the parser for the Zip Assembler, zasm.
|
| 9 |
|
|
// Since then, I discovered Flex and Bison and have written a
|
| 10 |
|
|
// parser using those tools. The true parser may therefore be
|
| 11 |
|
|
// found in zasm.y. This file, however, still declares some
|
| 12 |
|
|
// very valuable tools. In particular, all of the routines used
|
| 13 |
|
|
// to build instructions from the appropriate fields are declared
|
| 14 |
|
|
// in this file.
