Re: Weird stuff on command definition.

Now everything is fine except for the Start and End Date Time fields.

I get something like this. The element size is screwee and there is 4-bytes of garbage and the starting and ending dates are reversed.

Not garbage. Offset values. One for each element. The reversed element values is what I would expect.

Is there something I don't understand about the command definition? Shouldn't each element start with a two byte length followed a 7- byte date and 6-byte time?

Simple lists start this way but you have defined a complex list (i.e., a list of lists).

I think I have a bug in the command language but wanted to ask people is they saw a problem before I called IBM.

Highly unlikely. You are simply not processing the data structure correctly. It is not passed as you might expect but rather is prefixed by offset fields. Rather than explain it all here I suggest you explore the CL Programming manual in the chapter on command definitions--used to be Chapter 9 but I don't know the current location. You need to examine the section on complex list structures. This is documented rather well but you do need to think about it.
