OK, so I understand that EIntOverflow is raised *only* when longint variables capacity is exceeded, and in the case of booleans ERangeError must be checked instead. Is that so? Another question that I want to ask is why the following primitive sample seems to work as expected but does not produce any output on Solaris (using 1.0.6). ------------------------ uses sysutils; var i,k : Integer; x:real; begin i:=0; try x:=k/i; except on Edivbyzero do writeln('div'); on Exception do writeln('other'); end; end. ------------------------ BTW, is there any chance that some Solaris binary distro newer than 1.0.6 can be obtained? I tried to compile it myself but failed as it seems that my compiler (and its RTL) are not sufficient to build the new one.
