O_RD

 Function
  Set the open for read access flag in a FCREATE/FOPEN/FAPPEND statement.

 Value
  0 = 0b = 0o = 0h

 Remarks
  Files may be opened for read, write or combined read/write access.
  You should only use the access you need to allow other processes to
  open files at the same time in multitasking and networked environments.
  This constant will allow your PPE to read from a file without writing
  any information out to it.

 Example

  FOPEN 1,"FILE.DAT",O_RD,S_DN ' Open for read access
  FOR i = 1 TO 10
   FGET 1,s
   PRINTLN s
  NEXT
  FCLOSE 1
