Since the variable is defined as
&BLKSIZE
The numeric value for the block size specified on the DD statement,
dynamic allocation, or TSO ALLOCATE, ranging from 0 - 2147483647 (KB).
Type: Numeric
Max value: 2147483647
I am not sure you can test for null.
But try testing for less than zero (this is just a WAG)
When (&BLKSIZE < 0) Then ...

Subject: ACS routine question.
Hello,
I always find it difficult to find what I am looking for in the ACS routine
documentation.
I can check if a text keyword was not filled in in the allocation request,
e.g.: WHEN(&DATACLAS = '').
How do I check if a numerical keyword was not in filled e.g. &BLKSIZE?
WHEN(&BLKSIZE = '') is syntactically incorrect.
WHEN(&BLKSIZE = 0) not the same as 'not filled'.
I must be simple, but I cannot find it.
Thanks,
Kees.
