Hi ,

Is there a way to identify if a mainframe file is Binary or ASCII ?

We have to SFTP the file from Mainframe to Windows server and file is coming from different application , its a huge file and we are not sure if any data can be binary or not ,

Just checking , if there is any easy way to find out.

In any case it's binary, but may contain only EBCDIC/ASCII characters.

If you have DFSORT in your shop, and z/OS 2.4+, you can try a RegEx against the dataset. Make use of character class [:cntrl:]

Also, you can try to open the dataset in ISPF VIEW/EDIT session. For non-EBCDIC data you'll see the message about "non-printable characters".

ASCII data are not considered as valid text data in z/OS.

Thanks for the update. ISPF of course can also be used, have a look on the available pattern masks.
