I designate that your InputFile is a VSAM KSDS File.
And also there is only PrimKey=Name and no AlternateIndex.
I never heared of special alloance of reading a VSAM KSDS File.
You can read it in direct or sequentiel way. But if you have any internaly restrictions in your company not using the seq.-reading, best is to create alternate Index.
Or, as guptae said, use the SORT utility first in one Step to sortout the
desired records, and then in a following step, execute your programm.
