As for as assembler is concerned , we have reads based upon
the type of file. VSAm,QSAm etc. If it is QSAM we can use
normal GETL and GETM witha DCB defined in the pgm. if it
is going to be a VSAM i guess it should be a AB along with
a RPL

There are two possible scenarios:
1) This is a classroom quesiton where you are expected to
do some research on your own, and not ask someone in the
cloud for the exact answer.
2) The question is too vague, and would require a full
essay to answer. Please be more specific.
