Unix command question on TAB content

[Former Member]

We found the following ABAP statemenet

DATA: our_unix_path_and_file_name(64) TYPE c,
           v_unixcmd(255) TYPE c,
           result(255) TYPE c OCCURS 100 WITH HEADER LINE.

CONCATENATE 'ls -al' our_unix_path_and_file_name INTO v_unixcmd SEPARATED BY space.

CALL 'SYSTEM' ID 'COMMAND' FIELD v_unixcmd
                ID 'TAB'     FIELD result-*sys*.

The question is: is result an internal table? if it's an internal table, then why it's defined as type c? And also what is included in this result after calling this UNIX command? it will list all the file content?

Thanks and we will give you reward points!

The fact that the result says "occurs 100" defines it as an internal table. It is an archaic way of declaring it, but still valid.

Hi,

The result you'll get is a list of files and attributes from a directory and it will be placed in an internal table.
