Arguments

 

destination-string

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

   Destination string into which STR$TRIM copies the trimmed string.
   The destination-string argument is the address of a descriptor
   pointing to the destination string.
 

source-string

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

   Source string which STR$TRIM trims and then copies into the
   destination string. The source-string argument is the address
   of a descriptor pointing to the source string.
 

resultant-length

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

   Number of bytes that STR$TRIM writes into destination-string,
   not counting padding in the case of a fixed-length string. The
   resultant-length argument is the address of an unsigned word
   into which STR$TRIM writes the length of the output string.
   If the input string is truncated to the size specified in the
   destination-string  description, resultant-length is set to
   this size. Therefore, resultant-length can always be used by
   the calling program to access a valid substring of destination-
   string.
