Re: Variable length MODS

I have no idea of the ratio of useable to unusable, but the INFDS does 
have the file's record count.  That'd allow you to at least be sure it was 
large enough.

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
