hello,
i am trying to image some data using imagr, and in successive attempts i have
received error messages that i do not know how to handle. the first message
that follows was for a DBCON data set that i was running. i then ran imagr
with only one of the data sets that was used in the dbcon file. that ran
until the second message came up and the program aborted.
below are the messages as they appeared in the session, followed by the
inputs that were used by imagr.
i am in the AOC in room 257. i will be attending the summer school, but i
may be here some of the time outside the school.
thanks
