.386C ?

[fatty]

I know what .386 directive does, and .386P.
So what is .386C (I saw .386r here also)?
There's no .486C, so I guess it enables coprocessor instructions?

Hi,

   According to the TASM 2.0 Quick Reference Guide, .386C
is the same as the .386 directive.  I assume MASM usage
is the same.

At least for ML 6.14 .386 and .386C set the same processor type.

I need to dig up the 4.0 or 5.x manuals, but I think the "C" means "constrained", ie limited to a subset of the instructions.

Hi,

   I don't have 4.0 or 5.0 manuals, but I do have the 3.0 manual.
It has .286C but not .286.  So constrained would mean no protected
mode instructions?  Anyway, As with STRUC (all versions) and
STRUCT (6.0 onwards) they are probably just synonyms.

Cheers,

Steve

The 286 did have a protected mode.

Hi Clive,

   How did you get or generate those lists?  I would like to
do that for earlier versions.

   How did you get or generate those lists?  I would like to do that for earlier versions.

I did these with some manual labour to clean/sort some strings cut with ZTREE's Gather function. Looking at 1.25 and 1.27, there seems to a table/index for the first character, and my recollection with 6.xx was that it used a tree decoding/parsing method.

Hi,

   Same with Version 3.0 as with your 1.x unfortunately.

Thanks,
