RE: Initialize array in D-Spec

When did IBM start allowing the %DIV to be used on the D specs?
This was supposed to be in V3R1 but never got put in as far as I know.
This would be wonderful if it works.

Titus,

Here is an example from a program of mine (with the individual field
names renamed to be generic for example).

The point here is that one data structure is used as an array for
validation checks.  And later when processing the group, I can perform
separate functions when checking if the group is equal to Group1 or
Group2 and so on (as opposed to comparing the value to vldOrdGrp(1) or
vldOrdGrp(2) and so on).

 *  The valid Order Documentation Groups defined.

D                 DS

D OrdGrpDS                       4a

D  Group1                        1a   Inz( 'H' ) Overlay( OrdGrpDS )

D  Group2                        1a   Inz( 'U' ) Overlay( OrdGrpDS:
*Next ) 
D  Group3                        1a   Inz( 'I' ) Overlay( OrdGrpDS:
*Next ) 
D  Group4                        1a   Inz( 'E' ) Overlay( OrdGrpDS:
*Next ) 
D  vldOrdGrp                          Like( OrdGrp ) Overlay( OrdGrpDS )

D                                     Dim( %div( %len( OrdGrpDS ):

D                                                %len( OrdGrp ) ) )

(OrdGrp is a file-defined field)


A more common version of this that I personally use is to not name the
values inside the data structure.
 *  The valid Order Documentation Groups defined.

D                 DS

D OrdGrpDS                       4a   Inz('H+
D                                          U+
D                                          I+
D                                          E')
D  vldOrdGrp                          Like( OrdGrp ) Overlay( OrdGrpDS )

D                                     Dim( %div( %len( OrdGrpDS ):

D                                                %len( OrdGrp ) ) )

Subject: Initialize array in D-Spec

Hi!

What is a good way to initialize an array with different values in the
D-Specs? I want to replace the old fashioned way with tables and
constant data at the end of the program. Another reason is placing the
array in an include-sourcefile. Here is my example. But it doesn't work:

d        ds
d #array    4    dim(3)
d  #value1                    like(#array) overlay(#array) inz('Val1')
d  #value2                    like(#array) overlay(#array:*next)
inz('Val2')
d  #value3                    like(#array) overlay(#array:*next)
inz('Val3')
