Command Memory

CFS provides an internal table (8192 bytes), into which all entered commands are stored. The user can access this "Command Memory" in two different ways:

a) sequential:

Press SHIFT + ENTER, if a DUE2 key is not available. If the command field was blank, the last, and then the second last command will be displayed, and so on.

b) associative:

Pressing Shift ENTER with an entry 'string' in the command field, the last, and then the second last command beginning with the character string 'string' will be displayed.

Entering a string with the wildcard character * (*string) will cause the last, and then the second last command which contains the character string 'string' in any position, to be displayed.

Repeatedly pressing Shift ENTER allows the user to scroll back as far as required in the command history.

Examples:

COMMAND : OC    Shift ENTER

displays the last Open Connection command entered.

COMMAND : *FILE  Shift ENTER

displays the last command that contained the character string 'FILE'.

e.g. /FILE ... or ONX/FILE ...

Load the contents of the Command Memory to the P-Keys

An entry from the Command Memory displayed on the screen can be stored in any free P-Key: 'Px:' or 'Px#'. x represents the one or two digit number of the desired P-Key. The entry displayed on screen from the Command Memory is transmitted with the DUE1 key. The entry will then be stored in the specified P-Key. Executing the entry as a command is, in this case, suppressed.

If the entry from the Command Memory is suffixed with *EM, or *EM*DUE, then the P-Key string will be suffixed with < or < DUE1 respectively.

The P-Key string will automatically be suffixed with < DUE1 if the prefix 'Px#' instead of 'Px:' is given.

Example:

The entry /STA 7813 is displayed on the screen from the command memory. Modifying the entry to P12:/STA 7813*DUE and sending it with DUE1 will result in /STA 7813 being stored in the key P12. On account of the *DUE, pressing P12 will automatically result in the entry being transmitted.

Data Protection: Subsequent removal of particular entries from the Command Memory for security purposes is possible: The entry to be removed is found with Shift ENTER. Pressing the K3 key will delete this entry from the Command Memory.

Full Screen Command Memory Output

Entering '--' before the search string will cause a complete screen (Maximum 24 lines) of entries containing the string to be displayed.

The following possibilities exist:

COMMAND : --       Shift ENTER

displays the last 24 entered commands.

COMMAND : --string   Shift ENTER

displays the last 24 commands which begin with 'string'.

COMMAND : --*string  Shift ENTER

displays the last 24 commands that contain the character string 'string'.

Pressing Shift ENTER again will display the previous screen containing the requested commands, and so on.

Notes:

One or more lines from the command memory can be loaded to any desired P-key equally well in Full Screen command memory mode. The procedure is the same as that described above ("Loading the command memory contents to P-keys").

For further information about the command memory, see the commands LM/SM (Load Memory/Save Memory) on page 7-/7-.

The KC command (Keep Command) is also important in connection with the command memory. This command sets an option in CFS such that the command field is not erased after entering a command. The previously entered command will remain in the command field until it is overwritten by spaces or another command.
