Arguments

 

cf_id

   OpenVMS usage:identifier
   type:         longword integer (unsigned)
   access:       read only
   mechanism:    by reference
   Address of a longword that NCS uses to identify a conversion
   function. The cf_id argument is required and can be obtained by a
   call to the NCS$GET_CF routine.

   All calls to the NCS$CONVERT routine and the call to the NCS$END_
   CF routine that terminates the conversion must pass this longword
   identifier. Upon completion, the NCS$END_CF routine releases the
   memory used to store the conversion function and sets the value
   of the longword identifier to 0.
 

source

   OpenVMS usage:char_string
   type:         character string
   access:       read only
   mechanism:    by descriptor
   Descriptor of source string.
 

dest

   OpenVMS usage:char_string
   type:         character string
   access:       write only
   mechanism:    by descriptor
   Descriptor of destination string.
 

ret_length

   OpenVMS usage:word unsigned
   type:         word (unsigned)
   access:       write only
   mechanism:    by reference
   Length of converted string.
 

not_cvt

   OpenVMS usage:word unsigned
   type:         word (unsigned)
   access:       write only
   mechanism:    by reference
   Number of characters in the source string that were not fully
   converted.
