Documentation. Itemize system-variables that do not have a standard name.
Description
Sorry for my bad English.
The BIOSVARS directive defines a list of variables based on the one defined in Grauw's MSX Assembly Page. The variables (or would it be better to call them constants?) found in the BIOS, most do not have a defined name.
Currently, the only way to query the name of these variables is to look for them in the source in the msx_bios_vars() function in dura.y (as indicated in the document).
It would make it easy to add a list of these variables to the document 2.5. Directives, where the .BIOSVARS directive is described.
Thanks for readme.
Proposed Solution:
BIOS System Variables
| Name | Address |
|---|---|
| CGTABL | $0004 |
| VDP_DR | $0006 |
| VDP_DW | $0007 |
| MSXID1 | $002B |
| MSXID2 | $002C |
| MSXID3 | $002D |
| Name | Address |
| :--- | ---: |
| CGTABL | $0004 |
| VDP_DR | $0006 |
| VDP_DW | $0007 |
| MSXID1 | $002B |
| MSXID2 | $002C |
| MSXID3 | $002D |
