Info

ACCESSThe value of 'APPEND' will be recognized and implies sequentialaccess and positioning after the last record of the file. Opening a filewith append access means that each appended record is written at theend of the file.ASSOCIATEVARIABLEThis keyword specifies an INTEGER*4 integer scalar memoryreference which is updated to the next sequential record number aftereach direct access I/O operation. Applies only to direct access mode.DISPOSE and DISPThese keywords specify the disposition for the file after it is closed.'KEEP' or 'SAVE' is the default on anything other thanSTATUS='SCRATCH' files. 'DELETE' indicates that the file is to beremoved after it is closed. The PRINT and SUBMIT values are notsupported.NAMEREADONLYRECL=lenTYPEThis keyword is a synonym for FILE.This keyword specifies that an existing file can be read but prohibitswriting to that file. The default is read/write.The record length given is interpreted as the number of words in arecord if the runtime environment parameter FTNOPT is set to "vaxio".This simplifies the porting of VAX/VMS programs. The default is thatlen is given in number of bytes in a record.This keyword is a synonym for STATUS.OPTIONAL 90The OPTIONAL specification statement (attribute) specifies dummy arguments that may beomitted or that are optional.SyntaxOPTIONAL [::] dummy-arg-listExamplesOPTIONAL :: VAR4, VAR5OPTIONAL VAR6, VAR7INTEGER, OPTIONAL :: VAR8, VAR9116 Chapter 3
