Parsing or generating _really_ _big_ XML data streams?
In a CICS Web Services provider scenario, one could posit a very large 01
level, only some of which gets filled in for any one request...
01 Work-Areas.
05 Some-Table-Nb PIC 9(008) COMP-5.
05 Some-Other-Table-Nb PIC 9(008) COMP-5.
05 Marks-Nb PIC 9(008) COMP-5.
01 Response.
05 Personal-Info.
10 Given-Name PIC N(80) USAGE NATIONAL.
10 Family-Name PIC N(80) USAGE NATIONAL.
05 Some-Table Occurs 0 To 200 Depending Some-Table-Nb.
10 Photo-Base-64-JPEG PIC X(20480).
10 Fingerprint-base-64-JPEG PIC X(40960).
10 Scars-Marks-Tattoos Occurs 0 To 100 Depending Marks-Nb PIC
X(20480).
05 Some-Other-Table Occurs 0 To 10 Depending Some-Other-Table-Nb.
10 MPEG4-encoded-somehow PIC X(1024000).
05 [more big-ish data here]
But I'm just making this up, AFAIK we don't have anything like this.
One could also posit a video rental business that keeps the videos in DB2 BLOBs
and serves them via CICS Web Services COBOL applications. But I don't know of
any such business.
