I have found no better syntax.
"cat" is not among the utilities documented as supporting Classic
data sets; use at your own risk. It will likely not produce expected
results for both character and binary files. A form using a supported
utility is:
cp "//'dataset_name'" /dev/fd/1 | gzip -c > archive_name.gz
Additional options to cp can select character or binary mode, etc.

In an earlier submission to this thread I suggested using IEBGENER
instead of cat or cp. I formed the IEBGENER habit before Classic
data set support in cp was announced; it still retains the value
of supporting uncatalogued data sets and concatenations. You'd
need to write a wrapper (I use Rexx) to connect IEBGENER to gzip.
Then you might have the added value or connecting gzip directly to
FTP with no need for a temporary archive-name.gx.
