The present post about SAP ABAP Syntax check is in continuation with previous post of Syntax check for OPEN.
Addition 4
... IN BINARY MODE
Effect
The contents of the file are not interpreted by the read and write operations READ DATASET and TRANSFER . The data areas specified with these key words are directly input or output. The addition IN BINARY MODE does not have to be specified explicitly.
Addition 5
... IN TEXT MODE
Effect
If a file is opened with this addition, the system assumes that the file has a line structure. Each time READ DATASET or TRANSFER occurs, exactly one line is input or output. If the data area is too big for the line read, the remaining area is padded with blanks. If it is too small, the remainder of the line is lost.
Addition 6
... AT POSITION pos
Effect
This addition allows you to specify an explicit file position pos in bytes from the start of the file. The next read or write operation then occurs there. You cannot specify a position before the start of the file.
Although this addition can also be used with the addition IN TEXT MODE , it makes little sense, because the physical format of a text file depends largely on the operating system.
Addition 7
... TYPE attr
Effect
In the field attr , you can specify further file attributes. The contents of this field are passed unchanged to the operating system. No checks are performed. See the documentation of the fopen command for the relevant operating system.
Example
Generate a MVS file " 'QXX.YYY' " with the specified
attributes. (The apostrophes ['] are part of the file name.):
OPEN DATASET '''QXX.YYY'''
TYPE 'lrecl=80, blksize=8000, recfm=F'
FOR OUTPUT.
Addition 8
... MESSAGE msg
Effect
Stores the relevant operating system message in the field msg if an error occurs when opening the file.
Example
DATA: DSN(20) VALUE '/usr/test',
MSG(100).
OPEN DATASET DSN FOR INPUT MESSAGE MSG.
IF SY-SUBRC <> 0.
WRITE: / MSG.
STOP.
ENDIF.
Addition 9
... FILTER filter
Effect
Under UNIX and Windows NT, you can specify an operating
system command in the field filter .
Example
Under UNIX
DATA DSN(20) VALUE '/usr/test.Z'.
OPEN DATASET DSN FOR OUTPUT FILTER
'compress'.
opens the file DSN and writes the output data to this file via the UNIX command 'compress'.
Addition 4
... IN BINARY MODE
Effect
The contents of the file are not interpreted by the read and write operations READ DATASET and TRANSFER . The data areas specified with these key words are directly input or output. The addition IN BINARY MODE does not have to be specified explicitly.
