The two uses of DSNTYPE I can find are
<https://www.ibm.com/docs/en/zos/2.1.0?topic=file-dsntype-operand>
Identify the file type as either PIPE (a FIFO file) that is coded in
combination
with the PATH operand or
as an HFS (hierarchical file system) specified in combination with the
DSNAME operand.
HFS indicates that the data set is an HFS data set which contains a z/OS®
UNIX
hierarchical file system.
( I believe the latter is obsolete and not what you intend. You didn't specify
DSN.)
DSNTYPE does support other values (for example LIBRARY, PDS, EXTREQ,
EXTPREF, LARGE, and BASIC), but these are not appropriate for HFS files.

I'm too familiar with that for LRECL too small. It should have a different M&C
because
RECORD historically meant "block" when that message was issued.

If it doesn't work it deserves an SR. Can you Edit/View files so tagged with
ISPF?

I'd say you underestimate IBM, but I've had too much unpleasant experience
overestimating
IBM in such matters. BTW, DCB=(LRECL,...) is incompatible with PATH. WHY!?

At least complete examples for IEBGENER SYSUT1 and HLASM SYSLIB, both showing
examples
of mixed concatenation. The best I find easily is in Using Data Sets:
//SYSUT2 DD PATH='/sj/sjpl/xsam/xpm17u01/paytime',
// PATHDISP=(KEEP,DELETE),
// PATHOPTS=(OCREAT,ORDWR),
// PATHMODE=(SIRUSR,SIWUSR,
// SIRGRP,SIROTH),
// FILEDATA=TEXT

There used to be such a matrix, in the JCL Ref., IIRC. Perhaps it outgrew page
size
and IBM simply dropped it in favor of scattered "Relationship to other
parameters"
sentences.
