Re: EXTNAME ( MyDSPF : MyFormat ) -- RPG400-L

CLEAR will never cause blanks to be placed in a zoned character field.

RESET on the other hand will, unless INZ is specified.

"The CLEAR operation sets elements in a structure (record format, data
structure, array, or table) or a variable (field, subfield, array
element or indicator), to their default initialization value depending
on field type (numeric, character, graphic, UCS-2, indicator, pointer,
or date/time/timestamp). For the default initialization value for a
data type, see Chapter 10, “Data Types and Data Formats,” on page
169."

"The RESET operation is used to restore a variable to the value held
at the end of the *INIT phase. This value is called the reset value.
If there is no *INZSR subroutine, the reset value is the same as the
initial value"

Even if you're using INZ, CLEAR MyDS will cause blanks in your zoned character field. Try using INZ with RESET.

Subject: EXTNAME ( MyDSPF : MyFormat )

Hi, all.

I just added a DS to a procedure with the idea that it would be populated automatically when the user enters data. In the record MyFormat is one zoned decimal field, all the rest are character fields.
At the EXFMT MyDSPF, I get MCH1202.

The code is basically this :
D MyDS E DS EXTNAME ( MyDSPF : MyFormat:*INPUT )

/FREE
MyNumField = 0;
EXFMT MyFormat;

While debugging, there seems to be confusion between MyNumField of MyDS and MyNumField of MyDSPF. If I do EVAL MyNumField at the EXFMT, I see that MyNumFld = 0. If I step into the EXFMT, and then type EVAL MyNumField, I then see that MyNumFld = blank. I've tried INZ on the MyDS declaration and also CLEAR MyDS.

What am I doing wrong? Is there a better way?

In the DSPF there are many many field names that occur in different record formats.
For that reason, I wanted to store the contents of MyFormat in a global qualified DS.

Thanks
