Re: Issue with %NULLIND

I will take a look at that John, 
But it is not related to the H spec, I have an h spec at the top of the 
module that has the allnull.

It is not related to your problem (this time anyway) - others have 
already pointed out the issue there.

However, I noticed in your code that you have a "naked" d data type in 
your PI (i.e. one with no DATFMT specified).  Unless you can 
absolutely guarantee that nothing but an ISO date format will ever be 
used by any program in your system this is a dangerous practice. A 
naked d means use the default format - but the default can change from 
program to program based on their H-specs. As a result, the prototype 
that should protect you from passing an invalid date format into a 
routine will fail to do its job if the PI/PR rely on defaults.

Personally I'd also specify the other data types in the PI/PRs - but 
I'm just a cranky old man.
