Writes the specified data  to  the  output  file  indicated  by  the
  logical name.  The data is written as one record in the output file.

  Format:


    WRITE  logical-name expression[,...]

ParametersCommand QualifiersExamples

 logical-name

  Specifies the logical name assigned to the file to which a record is
  to  be  written.   Use the logical name assigned by the OPEN command
  when the file was opened.  (The OPEN command assigns a logical  name
  to a file and places the name in the process logical name table.)

  In addition, you can specify the process-permanent files  identified
  by   the   logical   names  SYS$INPUT,  SYS$OUTPUT,  SYS$ERROR,  and
  SYS$COMMAND.

 expression[,...]

  Specifies data to be written as a single record to the output  file.
  You  can specify data items using character string expressions.  See
  Section  5.7.1  of  the  VAX/VMS  DCL  Concepts  Manual   for   more
  information on string expressions.

  You can specify a list  of  expressions  separated  by  commas;  the
  command  interpreter concatenates the items into a single record and
  writes the record to the output file.

  The maximum size of any record that can be written is less than 1024
  bytes,  unless  you specify the /SYMBOL qualifier, in which case the
  maximum is 2048 bytes.  (See the "Description" section below.)

/ERROR/SYMBOL/UPDATE

 /ERROR=label

 Specifies a label on a line  in  the  command  procedure  to  receive
  control  if  the  write  request  results  in an error.  If no error
  routine is specified and an error occurs during the writing  of  the
  file, the current ON condition action is taken.

  The error routine specified for this qualifier takes precedence over
  any action statement indicated in an ON command.

  If an error occurs and control passes  successfully  to  the  target
  label,  the  reserved global symbol $STATUS retains the code for the
  error that caused the error path to be taken.

 /SYMBOL

 Causes the expression to be interpreted and its expanded value placed
  in  a  2048-byte buffer before the write operation is performed.  If
  you specify multiple expressions, their values are concatenated  and
  placed  in  the  2048-byte buffer.  Use the /SYMBOL qualifier if you
  need to write a very large record (see the  preceding  "Description"
  section).

  Each expression specified must be  a  symbol.   You  cannot  specify
  character  string  expressions (that is, strings in quotation marks)
  with the /SYMBOL qualifier.

  If you do  not  use  the  /SYMBOL  qualifier,  the  entire  command,
  including  the  expression  or expressions, is placed in a 1024-byte
  buffer, as explained in the "Description" section.

 /UPDATE

 Specifies that an existing record be  modified  (updated)  using  the
  specified  record.   You must be able to read and write to a file in
  order to use the /UPDATE qualifier.  You can  use  the  WRITE/UPDATE
  command  only  after  a  READ  command.   The  WRITE/UPDATE  command
  modifies the last record you have read.

  With sequential files, you must replace a record with another record
  of the same size when you use the WRITE/UPDATE command.

  1.   $ WRITE SYS$OUTPUT "Beginning second phase of tests"

  The WRITE command writes a single line of text to the current output
  device.

  2.   $ OPEN/APPEND OUTPUT_FILE TRNTO::DBA1:[PGM]PLAN.DAT
       $ WRITE OUTPUT_FILE "BEGINNING PHASE 3"

  The OPEN/APPEND command opens the file PLAN.DAT at the  remote  node
  TRNTO,  and positions the pointer at the end of the file.  The WRITE
  command writes a record to the end of the file PLAN.DAT.

  3.   $ OPEN/APPEND MYFILE [JONES]TESTING.DAT
       $ WRITE/SYMBOL MYFILE A,B,C

  This example assumes that the symbols A, B, and C have already  been
  defined.   The OPEN/APPEND command opens the file [JONES]TESTING.DAT
  and positions the pointer at the end of the file.  The  WRITE/SYMBOL
  command  concatenates  the  values  of  the symbols A, B, and C, and
  writes this data to a new record at the end of the file.
