Kindly help me out on the below reqmnt

# i want to dynamically creat a JCL
# depending on number of records in the input file..
# the jcl should create number of output files
# i meant allocate..
# like for every 25000 records in the input file
# a output file should be allocated and first 25 k records should be put into that
# we need to write a cobol pgm but how to pass the number of records read from the program to the JCL ????

# i want to dynamically create a job
OK

OK

# an output file should be allocated and first 25K records should be put into that
OK

Why? What is the purpose of this program? And, if you are writing this program, why can't it dynamically allocate the datasets and write out the 25K records to each one? Why bother with the JCL?

# can we use any JCL count is there anything like that?
You can use the COUNT and dataset splitting features of DFSORT/ICETOOL. There have been posts of similar scenarios that have already been addressed.
