GDDM V3R2 Base Application Programming Reference

Function

To change field status.


   ASFMOD      (field-id, mod)

   APL code               412
   GDDM RCP code          X'0C081100' (201855232)

Parameters

field-id (specified by user) (fullword integer)
The number of the field to be affected. If this parameter is zero, all of the unprotected fields (type 0) on the current page are affected.

mod (specified by user) (fullword integer)
The new setting of the modify attribute. Possible values are:

0

Make the field (or fields) unmodified.

1

Make the field (or fields) modified.

Description

Designates an alphanumeric field (or fields) as modified or unmodified. A modified field is added to the list of modified fields. The field is then available to ASQMOD as a modified field. The other way in which a field can become modified is by operator changes. Modified fields become unmodified when they are returned by ASQMOD. An unmodified field (the initial status) is not returned by a call to ASQMOD.

Under CICS/VS and IMS/VS, GDDM causes the physical modified data tag (MDT) bits to be set for fields that are designated as modified so that the fields can be returned as input to a subsequent application program after GDDM terminates.

Under OS/TSO and VM/CMS, GDDM does not generally cause the physical MDT bits to be set for fields that are designated as modified.

Principal errors

ADM0209 E: FIELD IDENTIFIER n IS NEGATIVE
ADM0211 W: {FIELD n1} ATTRIBUTE {n2} VALUE n3 IS INVALID
ADM0212 E: FIELD n DOES NOT EXIST
