[daip] error on aips

[Kazuya HACHISUKA]

Dear AIPS staffs, 

I am AIPS user on SUN. 
I have used AIPS without any problems up to now. 
However, suddenly the AIPS do not work for any commands. 

The error message are following :
------------
>tget possm
AIPS 1: ZDIR: COULD NOT TRANSLATE LOGICAL =
AIPS 1: ZDIR:
AIPS 1: ZTXMAT ERROR =      2
>inp
AIPS 1: ZDIR: COULD NOT TRANSLATE LOGICAL =
AIPS 1: ZDIR:
AIPS 1: ZTXMAT ERROR =      2
------------

The starting of AIPS is succesful with no problems. 
The AIPS version is 15APR99. 

I am trying to resolve this error, but I can't find 
cause of this problem. 

Please tell me to resolve above problem. 


Sincerely yours, 
Kazuya Hachisuka
