/sys$common/syshlp/helplib.hlb RTL Routines, SMG$, SMG$PUT_CHARS, Arguments  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 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 character
    string.

 start-row

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

    Specifies the row at which output begins. If start-row is
    omitted, output begins on the current row. 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

    Specifies the column at which output begins. If start-column is
    omitted, output begins on the current column. The start-column
    argument is the address of a signed longword that contains the
    column number.

 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 bit mask 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-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

 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.
