Re: [IDMSVENDOR-L] Get storage

Discussion created by ca.portal.admin on Jul 23, 2009
It may come to that. I'm not sure my assembler skills are up to it
though.=
:-)

We have a situation here where user programs need to pass XML to and
from s= ome common routines. The size of the XML can vary from a few
hundred bytes= to infininitely large. We are currently using a work
record for this purp= ose, which is the defined as the 32K (the maximum
work record size). This = is unsatisfactory for a couple of reasons:
- All of the user programs have to allocate the 32K in their working
stor= age which wastes a lot of space in many cases.
- 32K is not enough in other cases. Some XML documents are so large
that= it's not practical to try to fit them into pre-defined program
storage.

The XML parse and generate commands need to work on the entire XML
document= at once. So we can't break it up into pieces, which rules
out scratch and= queue records. Plus we need to keep it fairly simple,
so as not put an un= due burden on the programmers.

With a pointer and a length, you can define the storage field as one
byte i= n the linkage section, and manipulate the data using offsets.
This works g= reat with the XML parse command. I have done something
similar in CICS, bu= t I had access to the pointer and length values
there. I don't here.

I think an assembler program may be the only option. Other suggestions
wil= l be more than welcome!
