RE: User space, outfile or workfile

If you are going to use a user space why not just do this:

     D NUM_OF_FLDS     s              5I 0                                      
        Fields in the file
     D US_PTR          s               *                                        
                Pointer to user space

     D fld             ds                  Based(US_PTR)
     D   name                        10A
     D   type                         1A
     D   recpos                      10I 0
     D   size                        10I 0
     D   digits                      10I 0
     D   decpos                      10I 0


     c                   for       x = 1 to NUM_OF_FLDS
     c                   eval      mame   = *blanks
     c                   eval      type   = *blanks
     c                   eval      recpos = 0
     c                   eval      size   = 0
     c                   eval      digits = 0
     c                   eval      decpos = 0
     c                   eval      US_PTR += %Size(fld)                        
Move to next field
     c                   endfor

I have a hard time believing it would be slower and IMHO it more 
straightforward.

Okay, here's some sample code:

     D MAX_FIELDS      c                   256

     D fld             ds                  qualified
     D                                     DIM(MAX_FIELDS)
     D   name                        10A
     D   type                         1A
     D   recpos                      10I 0
     D   size                        10I 0
     D   digits                      10I 0
     D   decpos                      10I 0

     D x               s             10I 0

     c                   for       x = 1 to MAX_FIELDS
     c                   eval      fld(x).name   = *blanks
     c                   eval      fld(x).type   = *blanks
     c                   eval      fld(x).recpos = 0
     c                   eval      fld(x).size   = 0
     c                   eval      fld(x).digits = 0
     c                   eval      fld(x).decpos = 0
     c                   endfor

Obviously, you'd populate it from the data in the user space, and only
loop through the number of fields in the file... but I'm too lazy to
create an example that actually uses QUSLFLD...  hopefully this example
explains it well enough.
