Arguments

 

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.
