Arguments

 

keyboard-id

   OpenVMS usage:identifier
   type:         longword (unsigned)
   access:       read only
   mechanism:    by reference

   Keyboard identifier. The keyboard-id argument is the address of
   an unsigned longword containing the identifier of the virtual
   keyboard from which to read.

   You create a virtual keyboard by calling the SMG$CREATE_VIRTUAL_
   KEYBOARD routine.
 

replace-string

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

   String that contains the line to be entered into the recall
   buffer. The replace-string argument is the address of a
   descriptor pointing to this string. The default is a null string,
   which removes the last line entered.
 

line-count

   OpenVMS usage:byte_unsigned
   type:         byte (unsigned)
   access:       read only
   mechanism:    by reference

   Number of lines to be replaced. The line-count argument is the
   address of an unsigned byte containing the number of lines to
   be replaced with replace-string. The default value for the line-
   count argument is 1 (the last line entered).
 

flags

   OpenVMS usage:mask_longword
   type:         longword (unsigned)
   access:       read only
   mechanism:    by reference

   Specifies optional behavior. The flags argument is the address of
   an unsigned longword that contains the flag. There is one valid
   value:

   SMG$M_KEEP_CONTENTS    The string specified by replace-string
                          replaces the existing string specified by
                          line-count. By using this flag in a loop,
                          the line recall buffer can be preloaded
                          with information by the application.
