I am extremely embarassed to be asking this, but I haven't worked with typed
files in so long that frankly I cannot remember.
Say I have this code:
Type someRec = record
I : Integer;
Var FoS : File of SomeRec;
Now lets say FoS contains three entries and I wish to remove the first one.
A simple shift up loop will technically remove it,
entry1 := entry2;
entry2 := entry3;
But how do I then get rid of the duplicate entry two ?
In other words, next time a record is added how do I ensure that it is added
at the third position in the file and not the fourth ?
