dual entry asm routine

I have this case of two virtually identical routines that must run at the ultimate speed.

One approach would be:

           RSEG ?DT?FormatBitSegment
FBSfcol:   DS    1

           RSEG  ?PR?FormatBitSegment?AVFMTBS
           USING  0

FormatScrollSegment:
           ......
           mov   a,FBSfcol
           ......
           sjmp  common

FormatBitSegment:
           ......
           mov   a,FBSfcol
           .......
common:    .......
           ......
           mov   a,FBSfcol
           ......
           ret

The question is not does it work, but is it legal re local storage etc..

Thanks in advance,

Erik

Surely this is how the "Common Tail Merge" optimisation works?
So it must work!?

Thanks, Andy

Would it not be absolutotally wunnerful if the manual index had cross references to "the same with other words"

sort of a cross between an index & a thesaurus?

That'd be really useful!

No, local storage can get confused. How about using F0 in the PSW for your flag?

Jon,
No mention of a flag in my post, what are you talking about ?
