After reading a bit more of you code, I need to change some of the details
of my suggestions.
Immediately above your definition of 'paint' in tgsjhs.ijs you have:
ev_command_enter=: 3 : 0
". s=. getv 'command'
)
At the bottom of your 'paint' definition you have the line:
jhrajax linecolors,JASEP,lines,temp
What I am proposing is that you store these values (linecolors, lines,
temp) in your tgsj locale. You will have to change things slightly, so that
paint can run multiple times. And then run the modified jhrajax from
ev_command_enter.
Perhaps something like this:
ev_command_enter=:3 :0
PENDING=:''
". s=. getv 'command'
jhrajax PENDING
)
And then in 'paint' you would append data to PENDING.
Possibly you would need to get a little fancier than that - I've not
studied your code in enough detail to guide this process.
But this would let you run 'paint' as many times as you need, and still get
the "only one jhrajax" that your current design seems to need.
Does this make sense?
Thanks,
