I thought much the same when I initially read Jevgeni's message but then I 
thought the exception only occurs at page-overflow versus the alternative of an 
IF test on every write.  I suspect in this case the performance penalty is 
negligible -- although a test-case from an interested party might be 
informative 
:)

I also suspect that RPG is monitoring the message to set on the overflow 
indicator rather than counting lines and feel that using a similar process in 
your own code is acceptable.

My guideline for even worrying about exceptions is the old 80/20 rule.  If 80% 
of 
given operations could get an exception then check before-hand otherwise just 
catch the exception.  The real choice comes down to which method results in the 
cleanest code.

Regards,
Simon Coulter.
