<p><b>New page</b></p><div>Generates a header for popular calculator shells.<br />
<br />
The directive generates code (and inserts it at the current point) according to the list.<br />
<br />
/*Ion*/<br />
ret<br />
jr nc,Start<br />
.byte "Description",0<br />
Start:<br />
/*MirageOS*/<br />
ret<br />
.byte 1<br />
; 30 bytes for 15x15 icon.<br />
.byte "Description",0<br />
/*Venus*/<br />
.byte $E7,$39,$5F,$5B,$56,$3F,$00<br />
jr nc,Start<br />
.byte "Description",0<br />
; If specified, 32 bytes for 16x16 icon.<br />
Start:<br />
<br />
You still need to specify the start origin yourself. You will also need to manually add the AsmPrgm header for TI-83 Plus programs.<br />
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).<br />
