[daip] 31DEC99 IMAGR problem

[David Titterington]

A user running IMAGR in 31DEC99 AIPS, having just switched versions
from 15OCT99, finds that the new adverb ALLOKAY is not recognised,
and cannot be set:

------------
>task 'IMAGR'
>inp
...
...
AIPS 1: XPARM      *all 0                  Conv. function parms for x
AIPS 1: YPARM      *all 0                  Conv. function parms for y
AIPS 1: NITER         0                    Maximum # of Clean components
AIPS 1: BCOMP      *all 0                  Begin at BCOMP component
AIPS 1:                                    Specify for each field.
AIPS 1: MISSING ADVERB: TRY A 'COMPRESS' OR 'HELP NOADVERB' FOR INFO
AIPS 1: SYMBOL?       ALLOKAY

>ALLOKAY 0
AIPS 1: SYMBOL?       ALLOKAY
------------

We've checked that we do have current versions of .EXE and .HLP files
for IMAGR under 31DEC99.  Is there a way of getting round this problem
without clearing the AIPS environment and starting again?

Many thanks,
David Titterington.
