| As you have not shown us your script nor, if you are running it in batch, your JCL, we can only guess. I will not try. |

Please use the code tags when posting code and do not use highlighting but some indicator e,g, <=== on the line(s) in question.
Is the data set name correct? The message says it is not found. It is legal but at 43 bytes long only just - the max length allowed being 44 bytes. |

What message do you get when you press F1 when you get the invalid DSN message?
On the mainframe the maximum length of a data set name is 44 bytes. It is possible that the application wants a shorter name but only the documentation can tell you. |

ISPF dialog services provide many details that are not available in Rexx, such as performing a syntax check of a data set name. Most likely the message was actually triggered by this service, |

Since you are getting help when you press F1... the panel is using the VER function to verify the data provided.
Issue MSGID ON to see the message number associated with the message. |

If tis is the data set name that you typed in
| Code: |
| MW.SYSTEM.VFR.RM1716.ST.FR3OUT.D17213.T1251 |
and MW is your prefix then you need to surround the name with quotes. Otherwise the system prefixes the name with your userid thus making the name > 44 bytes. |
