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 handles are volatile & local to file reset - >that
was the point of my original email. Seems as if there is no solution?


Of course there is. As was stated earlier you need to make the
filehandle a global not a local variable. You could also handle it
differently and use a TStringList instead. 

 s: TStrings;

s :=
//do something with
line 12
