Arguments

 

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.
 

character-string

   OpenVMS usage:char_string
   type:         character string
   access:       read only
   mechanism:    by descriptor

   The character string to be inserted. The character-string
   argument is the address of a descriptor that points to the string
   to be inserted.
 

start-row

   OpenVMS usage:longword_signed
   type:         longword (signed)
   access:       read only
   mechanism:    by reference

   The row position at which to begin the insertion. The start-row
   argument is the address of a signed longword that contains the
   row number.
 

start-column

   OpenVMS usage:longword_signed
   type:         longword (signed)
   access:       read only
   mechanism:    by reference

   The column position at which to begin the insertion. The start-
   column argument is the address of a signed longword that contains
   the column number.
 

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 of the 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
 

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.
