I thought you could simply turn off error reporting altogether but I
must be thinking of MATLAB since I can't find any reference to this in
the docs.

But you could insert a CATCH statement somewhere to handle the error,
maybe write some info to a file, then stop execution. All without IDL
reporting an error. You would also have to set !EXCEPT=0 to suppress
reporting of math errors (which CATCH doesn't catch). You may want to
structure it so you can easily report errors when you are debugging.

pro test_error

debug=0

if (debug) then begin
theError=0
catch, theError
if (theError ne 0) then begin
catch, /cancel
goto, theEnd
endif
endif

openr, lun, 'c:\nofile', /get_lun

theEnd:

end
