Answer / saisankar

there are two ways to send data to the application prog.
1)parm (for small amount of data)
2)sysin(for large amount of data)

1)parm: is used to send the data to application prog
(eg;.cobol)

upto 100 characters.

2)sysin:is used to send the data to application prog
(eg;.cobol)

large amounts.

Answer / swathi

Also, in SYSIN we can give the data directly. But when you
are using PARM, the data is passed with the help of linkage
section to corresponding program.

Answer / vinay sonar

Maximum length of data that can be given using parm is 100
chatachers for more length use sysin.

Answer / muttaiah

Parm: is used to send only 100 chars max
Sysin: we can pass large amount of data. Say even a file.

when passing data from parm, there should be a linkage
section in cobol program.
whereas in case of sysin there should be an accept stmt for
each line in sysin.

Please do correct me if i'm wrong.

2)sysin:is used to send the data to application prog

large amounts.
examples:

1) using JCL with sysin. //sysin dd *here u code the parameters(value) to pass in to cobol program /* and in program
you use accept variable name(one accept will read one row)/.another way.
2) in jcl using parm statement ex: in exec statement parm='whatever' in cobol pgm u have to code linkage section in that for first value you code length variable and variable name say, abc pic x(4).it will take john inside to read next value u have to code another variable in the same way above mentioned.

Suppose a proc step has a DD statement like //ABC DD DSN=TEST.FILE1,DISP=SHR DSN=TEST.FILE2,DISP=SHR and the above DD name is overridden from the JCL as given below //procstepname.ABC DD DSN=TEST.FILE3 - Will the DD statement now have just TEST.FILE3 or it will be TEST.FILE3 and TEST.FILE2? Suppose if it is overridden twice like //procstepname.ABC DD DSN=TEST.FILE3 //procstepname.ABC DD DSN=TEST.FILE4 Will this give a JCL error? If not, what will be final output?
