Once you've done this, does the DSCB indicate secondary extents, so you can create more extents with MOD (whatever) with no SPACE on the DD statement? But I suppose that if the DSCB continues to say SPACE=(unit,(prim,0)) even with secondary extents allocated, that wouldn't work.
The format 1 DSCB has no provision for saving primary allocation amounts, only the type. The justification presumably was that once you have the primary space, the information is useless, and only the secondary matters.
