OPEN Statement

The syntax is,

 
OPEN([UNIT=]< integer >,&

		 FILE=< filename >, ERR=< label >, &

		 STATUS=< status >, ACCESS=< method >,&

		 ACTION=< mode >, RECL=< int-expr >)

where,

• < filename > is a string,
• < status > is 'OLD', 'NEW', 'REPLACE', 'SCRATCH' or 'UNKNOWN',
• < method > is 'DIRECT' or 'SEQUENTIAL'
• < mode > is 'READ', 'WRITE' or 'READWRITE'
• if the file is direct access the RECL must be specified,

For example,

    OPEN(17,FILE='output.dat',ERR=10, &
        STATUS='REPLACE', &
        ACCESS='SEQUENTIAL',ACTION='WRITE')
    OPEN(14,FILE='input.dat',ERR=10, &
        STATUS='OLD', RECL=iexp, &
        ACCESS='DIRECT',ACTION='READ')
