Generates a header for popular calculator shells.
Syntax
.ionheader "Description"
.mirageosheader "Description" [, "Icon.gif"]
.venusheader "Description" [, "Icon.gif"]
.doorscsheader ["Icon.gif"]
Remarks
The directive generates code (and inserts it at the current point) according to the following table.
| Shell | Generated Code |
|---|---|
| Ion | ret jr nc,Start .byte "Description",0 Start: |
| MirageOS | ret .byte 1 ; 30 bytes for 15x15 icon. .byte "Description",0 |
| Venus | .byte $E7,$39,$5F,$5B,$56,$3F,$00 jr nc,Start .byte "Description",0 ; If specified, 32 bytes for 16x16 icon. Start: |
You still need to specify the start origin yourself. You will also need to manually add the AsmPrgm header for TI-83 Plus programs.
The directive will report a warning if there is not two bytes output before this directive (TI-83 Plus) or if data is output before this directive at all (TI-83).
