One of our developers is running into a hard halt error, CEE0810, on a
reallocate statement. This is in a service program, which another
program is using CALLP to access. She has her pointer and array defined
as follows:
d array s 32a dim(32767)
d based(arrayPtr)
d arrayPtr s *
Does her initial allocation:
// allocate storage, if necessary
if wa = *zero;
wa = 100;
arrayPtr = %alloc(wa * 32);
endif;
And then reads records from a file using SQL. It's that data she's
going to store in the array. So, if it's determined she needs to store
more than 100 elements, the program attempts to reallocate:
if b2 > wa;
wa += 100;
arrayPtr = %realloc(arrayPtr:wa * 32);
endif;
The reallocate fails with CEE0810:
The starting address for reallocation is not valid.
Function check. CEE0810 unmonitored by PGMNAME at statement
0000000855,
instruction X'0000'
No one has any idea what the problem is, research has turned up nothing.
Could the problem be something like since this is a service program, and
it's on the 5th call to the service program that the reallocate logic is
executed, somehow the program has lost the location of the original
allocation so it doesn't know where to go to reallocate? There's no
other logic in the program that's manipulating the value of the pointer
other than the allocate and reallocate statements above.
Thanks for any ideas,
Lorraine
