Occurs

[Bernd Stoltefuss]

Hi again,

another question:
How do i address a field in an occurs section?

My copybook is like this:

01 BLA.
    02 REC.
        05 FIELD1         PIC X(10)
        05 GROUP1 OCCURS 10.
            10 FIELDX     PIC X(10).
            10 FIELDY     PIC X(20).
        05 GROUP2 OCCURS 20.
            10 FIELDY     PIC X(10).
            10 FIELDZ     PIC X(20):

I tried
layout.getGroupField("REC", "GROUP1 (1)", "FIELDX");
and
layout.getGroupField("REC", "GROUP1", "FIELDX (1)");

But both versions don't seem to find the field. As i never worked with occurs fields before i am not sure about the correct way to get the fieldDetail espacially as i have to adress it with it's group name, as it may occur in more then one group in the copybook.

May be i found nd the solution by dumping the fieldDetail incl. GroupName.
The correct way seems to be:
layout.getGroupField("REC", "GROUP1 (1)", "FIELDX (1)");

So the index has to be used on both group and field. Rather odd...

I have updated so that the following works:

• layout.getGroupField("REC", "GROUP1", "FIELDX (1)");

Also Group details are exported/imported in RecordEditor-Xml. They are exported as a Tag on the field item, but only when they change so you get

 <field ... group=".a.b.c.">
 <field ...>
 <field ...>
  <field ... group=".a.d.">
 <field ...>

it should be one of:

    layout.getGroupField("REC", "GROUP1", "FIELDX (1)");
or
   layout.getGroupField("REC", "GROUP1 (1)", "FIELDX");

but could well be

layout.getGroupField("REC", "GROUP1 (1)", "FIELDX (1)");

I will look at it and update to

layout.getGroupField("REC", "GROUP1", "FIELDX (1)");

Also with getGroupField you do not need to specify every Group level. Only specify the minimum to fully qualify the name. It tries to follow the "Cobol" convention.

Reasoning:

In Cobol adding in a Group level does not cause a problem, so people do it without thinking about it e.g.

        05 Birth-Data                   pic 9(8).

becomes

        05 Birth-Data-X.
            07 Birth-Data                   pic 9(8).
