Answer / keshar

Addition to above answer to read particular member in file
we can use OVRDBF command in CL. This will pointed out to
particular member and then we can do any operation.
Syntax:
OVRDBF FILE(file1) MBR(mbr1)

In RPG we can read particular member by keyword EXTMBR in F
specification.

The EXTMBR keyword specifies which member of the file is
opened. You can specify a member name, '*ALL', or '*FIRST'.
Note that '*ALL' and '*FIRST' must be specified in quotes,
since they are member "names", not RPG special words. The
value can be a literal or a variable. The default
is '*FIRST'.

The name must be in the correct case. For example, if you
specify EXTMBR(mbrname) and variable mbrname has the
value 'mbr1', the member will not be found. Instead, it
should have the value 'MBR1'

example:
Ffile1 IE K DISK EXTMBR('MBR1')
