Variable length MODS

I need to build several MODS (multiple-occurence data structures), but I don't know the number of occurences that I'll need for them until I read some data from a file.  Of course, I could just set the OCCURS on the D-spec to a high number, but would rather just create enough occurences to handle the data.

Something like this:

d Labels                         s                dim(NumLabels) inz

d Tot1DS                       ds               occurs(NumLabels) inz
d amt1                                       7  2    dim(7)

d Tot2DS                       ds               occurs(NumLabels) inz
d amt2                                       8  2    dim(7)

c*  Read thru labels file, counting all of the useable label records
c*  Store that count in NumLabels to give us the number of Occurs for each DS
