Record lock issue when performing lookup within current file

Josh,
If you are sitting on one record in a group and you want to update all
the records in that group, you can do lookups to each record and before
trying to post to them, check to see if the record you just found is the
current record number.
For example,
lookup mypo=myporecords k=(ponum) i=a -nxp 'index A is built on PO
Number and variable ponum is defined appropriately.
loopit If not mypo
Then: goto finish
if: mypo(1){"~" ne 1{"~" 'assumed number might be literal
then;goto finish
if: mypo(@rn) eq @rn 'this is checking to
see if I am looking at myself
then: 5=5+whatever;getnext mypo;goto loopit
If: 'this is
updating all the others.
then: mypo(5)=mypo(5)+whatever;getnext mypo;goto loopit
All this assumes you are on one of the records assigned to that PONumber
that you want to adjust.
Some things might cause this to conflict with other users. You want to
do your lookup in such way that you start on your PO number and go next
to next until you hit the next po number and then stop. If you are
looking at all the records, you could certainly hit another user's record.
I hope my rough programming is readable.
Another way to deal with record locking is to put the users in another
file entirely and just do lookups to the file(s) in question. I use
this method on complex processing and I know one user is never going to
be dealing with the data another user might use. Eliminates all kinds
of issues, but the programming can be a bit more complex since all data
must be pulled in, processed and written out again.
