The Write Double-Width Line routine writes a line of double-width
text to a virtual display.
Format
SMG$PUT_LINE_WIDE display-id ,text [,line-advance]
[,rendition-set] [,rendition-complement]
[,flags] [,character-set]
OpenVMS usage:cond_value
type: longword (unsigned)
access: write only
mechanism: by value
display-id
OpenVMS usage:identifier
type: longword (unsigned)
access: read only
mechanism: by reference
Specifies the virtual display affected. The display-id argument
is the address of an unsigned longword that contains the display
identifier.
The display identifier is returned by SMG$CREATE_VIRTUAL_DISPLAY.
text
OpenVMS usage:char_string
type: character string
access: read only
mechanism: by descriptor
Characters to be written to the virtual display. The text
argument is the address of a descriptor pointing to the text.
line-advance
OpenVMS usage:longword_signed
type: longword (signed)
access: read only
mechanism: by reference
Specifies the number of lines to advance after output. The line-
advance argument is the address of a signed longword integer that
contains the number of lines to advance.
rendition-set
OpenVMS usage:mask_longword
type: longword (unsigned)
access: read only
mechanism: by reference
Attribute specifier. The optional rendition-set argument is
the address of a longword bit mask in which each attribute set
causes the corresponding attribute to be set in the display. The
following attributes can be specified using the rendition-set
argument:
SMG$M_BLINK Displays blinking characters.
SMG$M_BOLD Displays characters in higher-than-normal
intensity.
SMG$M_REVERSE Displays characters in reverse video; that is,
using the opposite of the default rendition of
the virtual display.
SMG$M_ Displays underlined characters.
UNDERLINE
SMG$M_ Specifies invisible characters; that is, the
INVISIBLE characters exist in the virtual display but do
not appear on the pasteboard.
SMG$M_USER1 Displays user-defined attributes.
through
SMG$M_USER8
The display-id argument must be specified when you use the
rendition-set argument.
rendition-complement
OpenVMS usage:mask_longword
type: longword (unsigned)
access: read only
mechanism: by reference
Attribute complement specifier. The optional rendition-
complement argument is the address of a longword bit mask in
which each attribute set causes the corresponding attribute to be
complemented in the display. All attributes that can be specified
with the rendition-set argument can be complemented with the
rendition-complement argument. The display-id argument must be
specified when you use the rendition-complement argument.
The optional arguments rendition-set and rendition-complement
let the user control the attributes of the virtual display. The
rendition-set argument sets certain virtual display attributes,
while rendition-complement complements these attributes. If the
same bit is specified in both the rendition-set and rendition-
complement parameters, rendition-set is evaluated first, followed
by rendition-complement. By using these two parameters together,
the user can control each virtual display attribute in a single
procedure call. On a single-attribute basis, the user can cause
the following transformations:
Set Complement Action
0 0 Attribute set to default
1 0 Attribute on
0 1 Attribute set to complement of default setting
1 1 Attribute off
flags
OpenVMS usage:mask_longword
type: longword (unsigned)
access: read only
mechanism: by reference
Optional bit mask that specifies the action to take if the text
does not fit on the line. The flags argument is the address of
an unsigned longword that contains the flag. The flags argument
accepts the following values:
0 Does not wrap (default).
SMG$M_WRAP_CHAR Wraps at the last character on the line.
SMG$M_WRAP_WORD Wraps at the last space on the line.
character-set
OpenVMS usage:longword_unsigned
type: longword (unsigned)
access: read only
mechanism: by reference
Specifies the default character set for all text in this virtual
display. The character-set argument is the address of an unsigned
longword that contains the character set code. Valid values are
SMG$C_ASCII (default), and SMG$C_SPEC_GRAPHICS.
