NOEQUALS should be a valid token - it is rejected
EQUALS should be a valid token - it is rejected
OPTION Y2PAST=1951 EQUALS is accepted with a warning about EQUALS
The diagnostic is objecting to ???? "near" - near what ?

The problem is the NOEQUALS parameter.
There was an issue with how the “Skipped” parameters were handled.
This parameter is skipped in GCSort because the order is determined during the read phase, and the output always follows the read order—just like in a FIFO queue.
Currently, the OPTION values that are skipped are:
REMOVECC, CONVERT, EQUALS, NOEQUALS, NODETAIL

I’ll update the GCSort version in a few days.

[Ralph Linkletter]

Sauro is the default behavior EQUALS ?
That is that the order of identical keys is preserved ?

In zOS the default is NOEQUALS

The preferred defaults would be EQUALS - IMO

[Simon Sobisch]

EQUALS is implied within libcob as default, and I think GCSORT uses that part under the hood.

[Ralph Linkletter]

Simon I was speaking of sort keys.
Are you speaking of index file keys ?
Sort has to work a wee bit more to accommodate duplicate keys in a record sequential file.

I do not think that libcob would understand that SORT FIELDS=(393,4,Y2P,A) is the object of a sort key in a record sequential file. GCSORT does for sure :-)

Of course I could be wrong :-)

@sf-mensch I remeber this post ( gcsort is Fast ! ) and Simon, you mention several item you were working on at that time. Is there an Update on these?

Hi,
EQUALS and NOEQUALS are not supported in the current version of GCSort. The option is ignored.
The output sort is always handled in a way that preserves the read order. It’s as if the EQUALS option were always applied.
I’ve released a new version, as the previous one had some handling issues. The new version is 1.14.12b.
Best regards,
Sauro
