1. Diff b/w 9(4) comp-3 and s9(4) comp-3.

9(4) comp-3 takes 2 bytes and s9(4) comp-3 takes 3 bytes sign takes extra 1/2 byte and the remaining 1/2 byte is filled with 0.

Pls correct me if i am wrong.

question 2 is not clear pls explain clearly.

1.
s9(4) means it takes the value from -9999 to +9999.
9(4) means its max value is 9999.

but comp-3 means it takes hexadecimal format.
comp-3 is computed as (m/2 + 1/2)

both s9(4) ans 9(4) comp-3 takes 3 bytes of memory only.....

1) the S9... means that pos values will contain a sign of "C".
neg values will contain a sign of "D".

the 9... means that pos and neg values will contain a sign of "F".

7) I usually cade a special last rec, e.g. EOF or 999999 or STOP. Then test for it in the pgm.

Doing this allows a variable # of sysin "cards".
