Hi Sergei Antonov,
thanks for your mail, sounds like JWASM changed in interesting
ways... Would be interesting to also know why it did that ;-)

Here is your patch again:

The macro say is defined as follows:
say macro stroff ; :vararg
; MOVOFF_ di,<stroff>
mov di,offset stroff
call sayASCIIZ
endm
The macro MOVOFF_ is defined as:
MOVOFF_ macro reg,offs ; :vararg
ifnb <reg>
ifnb <offs>
ifdifi <offs>,<reg>
mov reg,offset offs
endif
endif
endif
endm
Can anybody explain why argument S_mousetype[si] apparently
worked with old versions of JWASM but no longer is working?
It seems that "mov di, <offset S_mousetype[si]>" goes wrong?

If the call above now needs explicit "word ptr", then why
does for example "call [XMSentry]" not trigger a similar
problem? Because the call above uses "[bx+someoffset]"?
I hope JWasm does not try to scale the offset by word ;-)

The value of AS at that point is "jwasmd -mt ", but I do not
know which version of MAKE you use. Might make a difference
in whether it passes ctmouse or ctmouse.asm in the $* part??
I just tested with JWASMD 1.80 for comparison, that one opens
file.asm if I give either file or file.asm as argument, but if
I give "file." as argument, it tries to open "file." without a
file name extension. Sounds useful, so why and when did JWASM
stop doing that?
