Don't know. Probably the developers will keep it, just for compatibility [if
you want to express the concern that someday the vars will be removed]. But
imo there are reasons to not keep it and to do it in a better way, some of
them I mentioned to you earlier. It's Borland-crt incompatible anyway. Not
that I have much to say in this issue, that's just my two cents.

Btw, a small question: why do you need the screenheight/width vars in Linux
then ? Wouldn't it be better to use the WindMax stuff there too (since it's
Under Windows [NT and other supported non-DOS OSes] it isn't as well..... it
may even change during program execution, what a progress since '92... ;-)

Depends on the complexity of the program (and with what constraints you are
satisfied, see another mail in that thread).
I personally don't have the need to port from TP to Linux; if I am coding in
this OS I'm not porting from DOS but trying to get Win32 stuff running
(somehow) or vice versa (somehow).
[A TP based RTL doesn't help much here. Porting a Win32 app via DOS to Linux
or so.... *lol*]

*g* So we're talking about all TP units which deal with some kind of OS or
user interaction..... [the latter can be considered as kind of the former
[Left from the TP RTL is the strings unit, not counting overlay (obsolete),
printer (dos dependant; isn't stated as 100% Linux compatible in the fpc
docs) and the turbo3 and graph3 (n/a with FPC, obsolete) unit. You save one
unit. Please correct me if I'm mistaken]
