There are so many utilities(ICetool, IDcams, Iebgener)
which we can make use to check whether a file is empty.

//Jobcard
//stepname exec pgm=idcams
//dd1 dd dsn=xxx.pds,disp=shr
//sysin dd *
print infile(dd1) count(1)
/*

Here the job will give a return code '0' if the file has
atleast 1 record and RC-4 if there are no records

Suppose you want to check whether any records are there
apart from header and trailer. then Make the count as Count
(3).

//sysin dd *
print infile(dd1) count(3)
/*
