I misled myself, perhaps by the description of "$T (modify) SUBMITLIB" in:
    
https://www.ibm.com/support/knowledgecenter/SSLTBW_2.4.0/com.ibm.zos.v2r4.e0za100/ch1jes2_24_disk.htm

And:

    These concatenations can contain any combination of partitioned data sets 
(PDSs) or file system paths. 
"paths"!?  Yaaay!  It's almost as if they forgot the 20th Century.

But, (Yaaay!): ... The concatenation supports any format PDS (LRECL and RECFM)
    that can be used to pass JCL into input processing.

    ... files in the path with 1-8 character uppercase file names that conform 
to
    standard PDS member names ...
I suspect that restriction can be circumvented with symlinks.

Are the lexical rules for JES commands the same as for "standard PDS
member names"?

IEBGENER is so nice!  It honors the label attributes!

Could you split it on multiple lines provided that your (emulated) terminal
doesn't insert extraneous blanks?
