What you really need to point to the Environment is PSP:$002C, it just so 
happened that in a COM file PSP and CSEG are the same, this is not the case 
in an EXE file. TP 4.0 has a variable call PrefixSeg which holds the segment
of the PSP, so something like this would work now:
var
  EnvPtr : pointer absolute PrefixSeg:$002c;

should do it for you, look at page 295 in your Turbo Pascal 4.0 manual...
