RTL Routines, SMG$, SMG$PUT_CHARS_MULTI

The Put Text with Multiple Renditions to Display routine writes
text with multiple renditions to the virtual display.
Format
SMG$PUT_CHARS_MULTI display-id ,text [,start-row]
[,start-column] [,flags]
[,rendition-string]
[,rendition-complement] [,character-set]
OpenVMS usage:cond_value
type: longword (unsigned)
access: write only
mechanism: by value
display-id
OpenVMS usage:identifier
type: longword (unsigned)
access: read only
mechanism: by reference
Identifier of the virtual display to be affected. The display-id
argument is the address of an unsigned longword that contains
this identifier.
text
OpenVMS usage:char_string
type: character string
access: read only
mechanism: by descriptor
Text to be output. The text argument is the address of a
descriptor pointing to the output string.
start-row
OpenVMS usage:longword_signed
type: longword (signed)
access: read only
mechanism: by reference
Optional row number at which to start output. The start-row
argument is the address of a signed longword containing this
number. If omitted, the current row number is used.
start-column
OpenVMS usage:longword_signed
type: longword (signed)
access: read only
mechanism: by reference
Optional column number at which to start output. The start-column
argument is the address of a signed longword containing this
number. If omitted, the current column number is used.
flags
OpenVMS usage:mask_longword
type: longword (unsigned)
access: read only
mechanism: by reference
Optional bit mask that specifies the action to take before the
specified text is output. The flags argument is the address of
an unsigned longword that contains the flag. The flags argument
accepts the following values:
0 Does not erase line (the default).
SMG$M_ERASE_TO_ Erases the remaining part of the line.
EOL
SMG$M_ERASE_LINE Erases the entire line.
rendition-string
OpenVMS usage:char_string
type: character string
access: read only
mechanism: by descriptor
Optional bit mask string that controls the video attributes.
The rendition-string argument is the address of a descriptor
pointing to the bit mask string. Each attribute set causes the
corresponding attribute to be set for the corresponding byte in
the text string in the display. The following attributes can be
specified for each byte using the rendition-string argument:
SMG$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.
rendition-complement
OpenVMS usage:char_string
type: character string
access: read only
mechanism: by descriptor
Optional bit mask string that controls the video attributes. The
rendition-complement is the address of a descriptor pointing to
the bit mask string. Each attribute set causes the corresponding
attribute to be complemented for the corresponding byte in the
text string in the display.
If the same bit in the same byte is specified in both the
rendition-string and rendition-complement arguments, rendition-
string is evaluated first, followed by rendition-complement.
By using these two parameters together, you can independently
control each attribute in a single routine call. On a single-
attribute basis, you 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
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$C_ASCII (the default) and SMG$C_SPEC_GRAPHICS.
