But if you need to work with only one file, you can get rid
of a global variable in the main module by just extracting
the relevant functions and the file handle into a separate
unit:

thanks all - btw it wasn't the real code just an example I made up , the
while loop wasn't needed- mistake!
But the q still remains - having three functions would still give the
problem I have now- that when doing a file_read (my function flag=1) would
say 'file not open' because the handle
In my eyes it is (very) unlogic.
Why don't you make 3 functions?
Something like this...
var filename : string; // global var for storing the filename
function file_reset( name : string ) : boolean;
function file_read( var eof : boolean ) : string;
function file_close : boolean;
Whith your examp
well why not make it a global variable in that unit's implementation?
implementation
var
f:text
.
then have a separate function to close the file.
