firstkey setll file
do until %eof
firstkey reade file
if %eof
leave
endif
...do stuff...
enddo
I like this a lot, because it also allows for this:
firstkey setll file
do until %eof(file)
firstkey reade file
if %eof(file)
leave
endif
if SkipCondition
iter
endif
...do stuff...
enddo
I can insert a skip condition and if I don't want to process the record,
I can just ITER to go get the next record. Also, I always put the
filename in my %EOF. It may be overkill, but I've gotten into the habit.
Note that you can also put a check in prior to the loop to check for no
records if that's an error condition:
firstkey setll file
if not %equal(file)
...no records, log error, exit...
endif
do until %eof(file)
