Hi Michael,

Not exactly sure what you are asking about - descriptors and auto
allocating.

The program processes about 800000 packets a day, which can update
several tables.
It runs continously reading udp packets from systems at remote
locations coming in over the internet.

It has a global
exec sql include sqlca;

then a number of functions that get called with each function having
it own

xxx( args,... )
{
EXEC SQL BEGIN DECLARE SECTION;
a bunch of variable
EXEC SQL END DECLARE SECTION;

with various EXEC SQL inserts, updates and selects.
with checks of sqlca.sqlcode to determine if the sql statement succeeded.

}
