This information describes the BMS-related standard attribute
and printer control characters, a bitmap for attributes, MSR control
value constants, and attention identifier constants.
The standard list DFHBMSCA makes it simpler to provide field attributes and printer control characters. Table 1 lists the symbolic names for the various combinations of attributes and control characters. If you need combinations other than the ones shown, you must generate them separately. To help you do this, see Table 2 for a bitmap of attributes. To find the value of an attribute constant, see the 3274 Control Unit Reference Summary GA27-2827.
You can get the standard attribute and printer character control
list by copying copybook DFHBMSCA into your application.
- For COBOL users, it consists of a set of 01 statements that can
be copied into the working storage section.
- For C users, it is included in applications as follows:
- For PL/I users, it consists of DECLARE statements defining elementary
character variables.
- For Assembler language users, the list consists of a set of EQU
statements.
You must use the symbolic name DFHDFT in the application structure
to override a map attribute with the default. You can use a high value,
such as X'FF', to reset the COLOR, HILIGHT, OUTLINE, PS,
SOSI, or VALIDN attributes to their default values. To specify default
values in a set attribute (SA) sequence in text build, use the symbolic
names DFHDFCOL, DFHBASE, or DFHDFHI.
