Answer / praveen kumar bejjanki

The members to be created in single pds depends on the
value of the directory block we mention while creating the
PDS. suppose if directory block=1 then we can have 5
members. if dir blk=2 then 11 members.
the formula for no of members for the directory block is
6*n-1 where n=value of directory block
if n=1 then mem's=6*1-1=6-1=5
if n=2 then mem's=6*2-1=12-1=11 and so...on...
Correct me if this is wrong...
I hope this is the way we calculate the members in a PDS.

Answer / sreerag p n

i think the total number of members in a pds is related to
the size of directory block. for example ....if you specify
the directory block as 1 then you can create 5 members
inside a partition dataset(pds).if you create more than 5(it
is possible) but you will get region abbend when you run the
job....
i hope this is correct.....

Answer / ram

actual formulae is

6n-1

here , n= no of directory blocks

max nuber of directory blocks is 5

then 6*5-1=29

i.e., you can create only 29 members in single pds file.


correct if me wrong
thanks,
ram.

Answer / yaswanth

it will on the directory blocks that we specify when
creating a pds for example if we specify 5 we can create 30
members in it that means per block we can create 6
members,if try to create more than that we will get se37 abend

Answer / bryan

Depends on what the PDS is used for. If PDS is updated with
ISPF and statistics are recorded you get less members.
Stats are stored in an optional user area of any given
directory block. Consider a LOAD library (no ISPF stats) -
you can get many more members in 1 directory block than a
PDS which you edit. A directory block is 256 bytes - 2
bytes for a count field followed by 3-21 directory entries.
Directory entries are comprised of 8-byte member name,
starting position of the member in the PDS, and some
optional data of up to 62 bytes.

I recommend using PDSE instead and no longer have to worry
about directory blocks and compressing your library.

Answer / ashish

above answer is right but the maximum number of members
that can created are 255 theorotically(ranade jcl book).And
practically can be more than 255.

Answer / rajasekhar pattem

yes..praveen is right.

Answer / gani

depends upon the size of the program in each member

we define the array like this 01 array 02 veg occurs 10 times 03 days occurs 6 times 04 cost pic 9(5). but why don't we write it as 01 array 02 veg occurs 10 times 03 days occurs 6 time 04 cost pic 9(5). is there any error will occur ,what is it? and why don't 01,02,03 not contain picture clause? if we put pic in those is there any error will occur what is it will occur?
