SET MINIMUM-ATTR Statement

The Working-Storage group item template for highlight and outline display attributes

must be defined in Working-Storage as follows:

01 WS-MINIMUM-ATTRIBUTE.

02 FILLER PIC 9(04) COMP.

02 IBM-BASE-ATTR PIC 9(04) COMP.

02 IBM-FIELD-REVERSE PIC 9(04) COMP.

02 IBM-FIELD-BLINK PIC 9(04) COMP.

02 IBM-FIELD-UNDERLINE PIC 9(04) COMP.

02 IBM-FIELD-OUTLINE PIC 9(04) COMP.

•

IBM-BASE-ATTR specifies the set of field attributes currently supported by the

C00 and previous releases of Pathway for terminals in the IBM 3270 family. If you

do not specify a SET MINIMUM-ATTR statement, the default value is IBM-BASE-

ATTR.

•

IBM-FIELD-REVERSE, IBM-FIELD-BLINK, and IBM-FIELD-UNDERLINE

specify the set of highlight display attributes available on terminals in the IBM 3270

family.

•

IBM-FIELD-OUTLINE specifies the set of outline display attributes for terminals in

the IBM 3270 family, specifically TOPLINE, LEFTLINE, RIGHTLINE,

BOTTOMLINE, and BOXFIELD.

A value of 1 is placed in the corresponding elementary item if that attribute is required.

For example, if you want reverse video and outlining, you move the value 1 into the

IBM-FIELD-REVERSE and IBM-FIELD-OUTLINE elementary fields. All other fields

are set to 0.

The mimimum level of support for highlight or outline display attributes does not

change until a subsequent SET MINIMUM-ATTR statement is executed, even if you use

a CALL statement to move between program units.
