General Remarks regarding CFS Commands

Using commands - entered in the COMMAND field of the file list - functions of CFS that are not directly connected with a particular data element can be executed. For example, moving the window within a data list, or searching the list for an entry.

CFS functions that have no connection with the displayed file list can also be called using commands. For example, calling software components as a subprogram of CFS (EDT, EDOR, LMS, PERCON,...), opening subtasks (LOGON to any userid), connecting to UTM and DCAM applications; for a complete description, see Chapter 9 "Connections").

Commands for displaying and modifying data elements can also be entered in the COMMAND field. For more details, see Chapter 8 "CFS Display/Editor".

Finally, general program modes can be set or reset in the CFS command field. See Chapter 18 "Modifying Parameters".

K-/F-/DUE-Keys

In CFS, the K1 key returns you to the previous hierarchical level.

              LST  NP        *|END

Display Mode ---> File list ---> Selection mask ---> End CFS.

           K1  K1         K1

Pressing the K1 key will stop further display of Help information, as well as further processing of I/IM Actions.

In a file list, the F2 key results in all the displayed file names being made overwriteable for the purpose of renaming.

In Display Mode, the F2 key will cause the contents of the displayed file to be made overwriteable (implicit Modify command).

Using the F3 key, the current screen can be captured to a Hardcopy File.

The Shift ENTER key displays entries from the Command Memory. Further information about this can be found in the section "Command Memory" on page 7-.

Blanks in Commands

Commands can be entered in free format. A command scanner ensures that one to three sequential blanks are removed from CFS commands. CFS works internally with this method of compressed command input. There is no space compression with BS2000 commands.
