●
Note on syntax:
– The following applies to both areas:
Relevant rows can be recognized by the "cpux" string (where x = characters "1-4").
This applies to both areas.
Valid delimiters for the entries are "blanks".
All other characters are interpreted as comment characters and start a comment up to
the end of the row
Row length: maximum 256 characters
– The following applies to the file name of a file DB:
The file name begins with "cpuX" (where X=1, 2, 3, or 4);
"cpuX" must first be defined in the rack/slot assignment of the CPU;
Length: maximum 64 characters (including "cpuX");
Maximum of 100 entries;
Permitted characters: letters "A-Z,a-z"; digits "0-9", "_", "."
● Mixing entries
You can also mix the entries for rack/slot assignment of the CPU and DB assignment.
The DB assignment must, however, always come
after
the rack/slot assignment of the
relevant CPU.
You could therefore enter the example as follows:
cpu1
cpu1db20
cpu1db35
cpu2
cpu2_test.dat
0
0
4
4
20
35
5
The following entry is, however, not permitted and would be rejected with an error message:
cpu1bd20
cpu1db35
cpu1
0
4
20
35
Note
Remember the notation:
•
Please note the capitalization (lower case for "cpu" and no leading blanks at the
beginning of the row). Otherwise the files will not be recognized.
•
The tabulator is
not
permitted as separator.
