Arguments

 

character-string

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

   ASCII control string, consisting of the fixed text of the output
   string and FAO directives. The character-string argument contains
   the address of a descriptor pointing to this control string.
 

resultant-length

   OpenVMS usage:word_unsigned
   type:         word (unsigned)
   access:       write only
   mechanism:    by reference

   Length of the output string. The resultant-length argument
   contains the address of an unsigned word integer that is this
   length.
 

resultant-string

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

   Fully formatted output string returned by LIB$SYS_FAO. The
   resultant-string argument contains the address of a descriptor
   pointing to this output string.
 

directive-argument

   OpenVMS usage:varying_arg
   type:         unspecified
   access:       read only
   mechanism:    unspecified

   Directive argument contained in longwords. Depending on the
   directive, a directive-argument argument can be a value to
   be converted, the address of the string to be inserted, or a
   length or argument count. The passing mechanism for each of these
   arguments should be the one expected by the $FAO system service.
