Can you check what is the value of r ?

Hi Bill Lam

Executing line 141 in jd.ijs:
(LIBJD,' jdlicense >x x *c') cd JDT;<jpath pk
_2

r = _2

I hope this helps.

At line 143:
NB. if. _2=r do. assert 0[echo evalkey end.

This should be evaluation key expired.
Please check the content of your jdkey.txt if it contains something like

evaluation - valid until : 2026 5 16

[William Szuch]

Hi Bill Lam

Jdkey.txt
a16151098468099434 evaluation - valid until : 2026 5 16

This jdkey.txt file is only in folder:
~addons/data/jd/

Or should it be in folder?:
~config/

[bill lam]

It should be inside ~config folder.

Today is 2026-5-18, the evaluation jdkey has expired. I think you should apply for a new evaluation jdkey.

Hi Bill Lam

 

Thanks for information and attending to my questions.

Great support.

I will apply to the J Database for a new evaluation jdkey.

There is a bug when an old key has expired. I will send you a new key later today unless you can wait till Wednesday.

[Eric Iverson]

Jd bug prevents automatically installing a new evaluation key. Install one manually as follows:

***

Run J sentences to set your Jd key:
   key=: 'a12510243413233105 evaluation - valid until : 2029 5 18'
   key fwrite '~config/jdkey.txt'
   
If that is in a folder that requires write permission,
you will need proper permission for the fwrite to succeed.

***

Thanks to Bill Szuch for prompt reporting of the problem with Jd keys.
