Answer / samay simant

answer 1) Linkage section is used to accept data from outside the program.either its parm part of Jcl or Call from any other programs,they pass data into called program thru linkage section only.

2)Comp is binary.its the type how system stores ur data.
pic s9(1)-->pics9(4) --occupies 2bytes
pic s9(5)---pic s9(8) ----4 bytes
pic s9(9)---pics9(18)-----8 bytes

comp-3 is for packed decimal data where each character occupies half byte and sign is stored in last nibble.

If wrong,plz correct me anyone
