Re: IRRPROFILE

Thank you very much for the reply.I wil try soon whatever you suggested and
let you know in case of any anomaly.
For the time being may i say that NOTE-1 in IRRPROFILE and NOTE-2 in
DCYTIMES are not valid in light of the explanation you provided just to
make sure that users in future are not confused.
Thank you and have a nice evening

As far as I could see you will hit the first hard limit once you go beyond =
300 intervals. From your example it didn&#39;t sound like that was the case=

Then compile that routine and you are ready to go.<br>
If you go very high in number you may hit some other limit, just pay attent=

I think this help. By the way, please check consistency of your results, ju=
