As detailed here IDCAMS has some requirements for the output-dataset of the PRINT statement that it enforces in a not too obvious way.

The default SYSPRINT is RECFM=VBA,LRECL=125, but as per above link

You can alter the defaults by placing other values in the DCB parameter of the SYSPRINT statement. You cannot, however, use a record format of F or fixed block (FB); those are changed to VBA.

Note the part after the semicolon: IDCAMS will automatically change all DCB-Parameters it does not like.

After playing around with the parameters it seems to be even more strict than stated above: Even RECFM=VB will be changed to VBA and all LRECLs less than 125 will be changed to 125.

P.S.: Do you really want to PRINT the dataset like this?

Try this:

The scale function, like almost all R functions, does NOT modify its argument but rather returns a value based on its arguments. So the attribute is going to be found in hitters_validation_nn rather than in hitters_train_nn. Look at

To remove non-numeric columns, perhaps something like this?

You add a default namespace using the WITH XMLNAMESPACES clause, with the DEFAULT keyword.
