All,
I am allocating a file dynamically using assembler and the file is named dynamically with time stamp and FTP'ed to a server.
Say, i have three steps,
step1
step2
step3
step1: Calls Assembler program - allocates two files internally
File1 - has application specific data
File2 - has the dynamically created FTP card with File1's name in it.
Note: File1's name will change in every run and the FTP card will be created in this step with file1's name in it.
step2: FTP's the file (file1) to a server using the FTP card (file2) created in step1.
Step3: I am trying to access file1 in JCL as a DD statement. How do i access this? Note: the file name i want is available inside file2 but i want to access this in JCL. is there any way to do this?
Note: I dont want to copy the file content into another file and use it in the jcl, i want to use the same file name. Please help.
Please help. |

make step 3 a separate job,
submitted after step 2, via intrudr
the jcl being modified (dd dsn) by step1.
you can not change jcl after it has been processed by jes and the job is started by the initiater.
actually, you can not change the jcl once it has been submitted to jes.
and don't tell me a site that allows the idiocy of dynamic filenames not documented via dd statements
does not allow submission of a job by a preceding job. |

| I don't understand. Why does the source dataset name have to change? Why can't it be static, and just let the target filename change? |

Kevin, are you actually questioning THE REQUIREMENT?  |

Actually, I'm fine with the requirement. It's the proposed solution I'm questioning. This isn't really that difficult a process to figure out. |

Yup !
Maybe there are bonus points for overly complicating the implementation. . . 
Or i've gotten lost again. . .

The requirement is given by the client themselves, They want us to dynamically create the source and destination file name.
Our standerda say, we cannot submit jobs internally

I can make step 3 a seperate job but how will i access the file name in JCL(step3 - which is a seperate job)? |

Hello,
Create the jcl (or the filename) for step3 before step3 is entered into the system. I believe with a bit of research with your scheduling people, you may be able to do this with relative ease.
Another possibility is that the "step3 info" be created early in the run and referenced in "step3".
Most of the systems i work with "send" files and do not dynamically allocate the files via assembler. . . |
