RE: how to code a "lookahead"?

Jim,

yeah, i know what you mean.  I had only one occasion to use lookahead in 20
years, and i can't remember why I used it - probably just to try it out.

I can't think of a good reason to use them now, especially when you
consider that they don't work for update files - and only for primary or
secondary files.  the only reason I would want to use them is to do some
sort of special processing on the current record and to be able to UPDATE
it before relenquishing control of it, based on the value of the lookahead.

regards,

rick
