Thanks. Setting HDS_SHELL to -1 fixes the problem for me.

Looking more deeeply (now that it is daylight). I have code in the perl
end that looks to see whether there is an I- or A-task attached at the
other end. If it is an I- it sends an ADAM message. If it is an A-task
(which it is) then the perl end tries to open the local parmater file to
extract the value.
As for Alan's comment concerning why the "+" is the obvious candidate.
This repeatedly failed for all the blazars I was reducing that had pluses
in but '-' was fine and all the other sources with underscores were okay.
