You mean like ADA? Indeed, I agree :P
No, I meant languages which are not able to give me bit level control
over a type and have to circumvent this restriction with either
awkward "macro magic" or even can't do nothing at all.
If I mean to set the write buffer water mark of the SDRAM controller
register, I'd rather write:
|SDRAM_Buffer_Control.WB_Watermark := Sixteen;
instead of
|SDRAMBufferControl := (SDRAMBufferControl and not WB_WATERMARK_MASK) or
| WB_WATER_MARK_16;
Not even to think of the much more cryptic C version.
Then use bitpacked records:
type TSDRAM_Buffer_Control=bitpacked record
{...}
end;
var SDRAM_Buffer_Control:TSDRAM_Buffer_Control absolute [$xxxxxx];
begin
{...}
SDRAM_Buffer_Control.WB_Watermark := Sixteen;
{...}
Just like Micha I'm not impressed about the Ada code, and it is
off-topic, this is and remains a Pascal newsgroup. Comparisons between
Pascal and other languages are on-topic, comparisons between C and Ada are
off-topic.
