[Gate-users] Interfile reader trap

[Alex]

Quick update,

After some experimentation, I realized that the trap occurred when I did NOT
read in a range translator prior to reading the interfile header file.  It
was kinda of a user's error.  However, one would expect Gate to behave
better by throwing a warning rather than trapping like that!!...
