RE: User spaces

[Vernon Hamberg <vhamberg@xxxxxxxxxxx>]

LOL - but it's really meant as an example of how IBM has used the idea of 
extended attributes. There are all kinds of *FILE objects. What 
distinguishes each type? The extended attribute. (MI gurus, please do not 
listen now!). When you look at WRKOBJ SOMELIB/*ALL, the list has an 
"Attribute" column - this is the extended attribute, for all intents and 
purposes. For programs this will be things like RPGLE, CLLE, CLP, etc. For 
files it will be things like PF, LF, DSPF, ICFF, etc.

One use of this kind of thing would be to distinguish one "kind" of user 
space from another, I suppose. The difference might be that each "kind" is 
organized differently - this is all under your control. But you could have 
a program that will use a different set of routines for one "kind" of user 
space than for another.

Here's an example of WRKOBJ that shows 2 user spaces I just created - 
copy/paste it into NotePad to see the columns - hope it does not wrap in 
your email client

 Opt  Object      Type      Library     Attribute   Text 

      CHKWRD      *CMD      VHAMBERGO 

      CRTUSRSPC   *CMD      VHAMBERGO 

      DBR         *CMD      VHAMBERGO               Display database 
relations
      LSTFLD      *CMD      VHAMBERGO 

      ANYTHING    *QMQRY    VHAMBERGO   SQL 

      TEST        *QMQRY    VHAMBERGO   SQL 

      USRSPC1     *USRSPC   VHAMBERGO   DSPFFD      User space for DSPFFD 
outpu
      USRSPC2     *USRSPC   VHAMBERGO   DSPFD       User space for DSPFD 
output

The "Attribute" column contains the extended attributes I set when I 
created the user spaces.

Note that the *QMQRY objects have an SQL attribute - the other possible 
value is PROMPT, IIRC. This derives from settings in Query Manager.

If you do a DMPOBJ, you will se a section in the spooled file called 
.ATTRIBUTE-  which is this value.
