1. Can we declare temporary dataset without name?
2. How can we declare a db2 data type(varchar) filelds in the cobol declaration?
3. Suppose we have a proc step,
//step1 exec procname
//d1 dd dsn=dsn1
// dd dsn=dsn2
// dd dsn=dsn3
// dd dsn=dsn4
How can we override dsn2 from job?
4. what is the datatype of S9(4)A(4) variable?
5. can redefines come before the occurs clause or vice versa?
6. In a Job there r 100 steps how can we execute only 28 , 60 ,and 96 steps ?
7. Can Proc A call to B and B TO C and C To A? Is it possible? I mean to say is to possible to call proc from another proc? |

I suggest that you try a DD with no DSN and see what the OS really generates. |

Hi.
2.
| Code: |
01 Var.
05 VAR-LENGTH PIC S9(4) COMP.
05 VAR-DATA. PIC X(SIZE)
|
3.
| Code: |
//STEP1.D1 DD DSN=DUMMY,
// DD DSN=dsn2,DISP=SHR
|
Correct me If I am worng .. |

Correct me if I am wrong ... |
The DD is a concatenation rather than a single dataset and special care is needed. The first DD DUMMY in your reply will end the concatenation. Also, the question was to override dsn2 from the step.
| Code: |
//STEP1.D1 DD
// DD DSN=dsn3
// DD DSN=dsn4

Hi DeeP,

As I remember a DB2 Var Char was defined:
| Code: |
01 Var.
49 VAR-LENGTH PIC S9(4) COMP.
49 VAR-DATA. PIC X(SIZE). |
Unless they changed it. |

The datatype is invalid - it won't compile. |

| The presence of the S in the field causes it to be invalid and flagged with an S level compiler error. I tested a PIC 9(4)A(4) field (without the S) and that compiles fine. |

expat,
For overriding the 2nd dataset in the concatenation, should n't it be something like this.
| Code: |
//STEP1.D1 DD
// DD DSN=new-dataset
// DD
// DD |
