Hi All,
I am new to assmebler. I have doubt how to pass the control card and how to process the same in assembler. My lead ask me to use control cards to pass the input from JCL, i don't know what is that? |

Control cards usually means 80 byte data records which are read from a file such as SYSIN. In this case you Open, Read and Close the file.
However, passing data from JCL usually means passing parameters e.g.
| Code: |
| EXEC PGM=YOURPGM,PARM='DATA' |
in which case R1, by convention is pointing at the parameter(s) passed.
You need to determine which of these methods your lead wants.
Garry. |
