Possibly none, but I thought that if an allocate was going to fail for 
some reason handling that before I started using libdefs would be
easier.  Otherwise I'd have to take more care which libdefs were 
then reversed.

Having said that, for simple dialogs I only allocated a single pds
then altlibbed/libdeffed that for each of the types of file within 
it, eg naming rexx execs Rxxxxxxx, skeletons Sxxxxxxx, panels 
Pxxxxxx etc.

I probably assumed that all the libdefs/altlibs would work,  if the 
alloc had worked.
