Enter another valid SCREEN COBOL picture to override the edit picture displayed.
The Pathmaker product automatically enters N in the Default column to the left of the
Screen Picture field.
Because actual data is never displayed in data fields during simulation or while you
are editing with the Screen Painter, the only change to the screen picture of a data field
that will appear in the Screen Painter is a change to the length of the data field. All
other changes will only appear in the generated application.
User Conversion
Enter a value between 0 through 32767 to associate statements in a user-conversion
Tandem Application Language (TAL) procedure with the data field. (Blanks indicate
that you do not want a user-conversion procedure to be associated with the data field.)
You can write a user-conversion procedure (or use an existing one) to make validation
checks or data conversions. The user-conversion procedure uses the value you specify
here to determine which statements are to be executed for this field. Refer to the
Pathmaker Programming Guide for more information about user-conversion procedures.
Screen Field Name
Enter a value for the name of this screen field.
If you leave this field blank, the Pathmaker software generates a name for the screen
field. (This generated name is not displayed on the Display detail screen.) Because the
name generated by the Pathmaker software is dependent upon the field’s relative
position on the screen, the name of the field could change if you change its position on
the screen. For requesters that are completely generated by the Pathmaker software,
this is an acceptable approach.
However, if you are writing code in a requester copy library that refers to the field,
you need a name for the field that will not change if the position of the field changes.
To specify such a name, enter a valid SCREEN COBOL screen field name that does
not begin with the Pathmaker prefix T9154-. The name must be unique and cannot be
the same as the current requester name or any reference object name in the current
context.
If you enter more than 25 characters, the Pathmaker product truncates the field name
to 25 characters and adds the suffix - n , where n is a number from 1 through 20.
Limiting the name to 25 characters helps preserve its uniqueness.
Possible ways to use screen field names in a requester copy library include coding the
TURN TEMP phrase in SCREEN COBOL to highlight specific data fields that contain
invalid data and using the screen field name with @CURSOR-FIELD or @CURSOR-
POSITION to send the cursor position to the service.
Help Text
Displays the first five lines of help text associated with this data field. Initially, this
field contains any help text specified in the field's DDL or SQL DDL HELP clause.
