Border Spec

From BR Wiki
Jump to: navigation, search

The "BORDER=spec" parameter represents an insertable syntax that specifies the visual characteristics of the window border, within the Open Window statement. The BORDER= keyword must be followed by one of four border specifications (as of 4.3 these work with CON GUI ON as well).

As of 4.2, BORDER= must be followed by S, D or B, which in turn may optionally be followed by a colon and attribute specifications.

Syntax

,BORDER={B|D|S|<corners>} [<attributes>]

Parameters

  • "B" indicates that the border is to be blank;
  • "D" indicates a double-line border;
  • and "S" indicates that a single-lined border be used.

"Corners" may be used for custom-designed window borders. The "corners" parameter is used to specify custom-designed borders for both I/O windows and field help windows. Two characters must be specified for this parameter: the character to be used for the top left corner of the window and the character to be used for the bottom right corner of the window. Business Rules fills in the rest of the characters for you. See Screen I/O for illustrations and more information about border types and border graphics specifications.

Also within the BORDER= syntax, the "attributes" parameter may be specified immediately after the border specification (no spaces). The attributes specified here will affect the visual display of the border itself. See Attribute (Screen) for syntax.

Legacy Use

As of 4.2, Border=H and "8 chars" are no longer supported except that a new OPTION 62 permits S, D, B, H or an eight character string followed by a colon and then attributes. For example:

,BORDER=S|D|B|H|8-chars[:attributes]

While the colon is actually optional, it is recommended for readability when attributes are included.
