Reference: Builder parameter list
As each builder is called by DFHTBS, a parameter list is passed. Unique data is passed to enable one builder module to be called for a variety of terminal types. The length of the builder parameter list is fixed for each kind of subroutine; for example, the parameter list passed to BSEBUILD is always X'23' bytes long, regardless of the builder involved.
| Subroutine | Length of parameter list (hexadecimal) |
|---|---|
| BSEBUILD | 23 |
| BSECON | 13 |
| BSEDESTR | 7 |
| BSEMAKEY | B |
| BSEREADY | 3 |
| BSEUNRDY | 17 |
| BSEFINDF | F |
| BSEFINDN | B |
| BSEFLAT | B |
| BSEUNFLA | 27 |
| BSENQIRE | 7 |
