Re: [ferret_users] "let" converts "d" to "k"?

Hi Olivier,

Many thanks!

I found we can just use "... if k eq ..." in stead of "... if DUMMY_PR1
eq ..." to reduce waiting time. So that we can also omit the first
sentence and just use "let/quiet DUMMY_PR1 = if k eq 1 then PR1" to
start.

We then just need to specify k when using the variable PR or DUMMY_PR*,
since ferret seems to think k is unlimited for them.

Cheers,
Tony
