Reference: |
The Session Monitor has a number of commands for displaying the contents of the stack. These commands move an internal pointer forward and backward and display the contents of the stack starting at the location of the pointer (the Session Monitor commands themselves are not appended to the stack).
Initially, the pointer resides at the bottom of the stack (after the most recent entry). You can always reset the pointer at the bottom by pressing Enter.
Session Monitor categorizes terminal lines as one or more of the following:
You can enter Session Monitor commands at any time during a FOCUS session, except when you are using special full-screen facilities, such as FIDEL, Hot Screen, or TableTalk. You can even enter Session Monitor commands while being prompted for data or in the middle of entering other FOCUS commands, as in this TABLE request:
TABLE FILE CAR PRINT CAR /PC
If you enter a Session Monitor command during a data prompt, press Enter to return to the prompt.
You can include Session Monitor commands in FOCEXECs.
The following table lists the Session Monitor display commands:
|
Command |
Command Name |
Description |
|---|---|---|
/PP |
Previous Page |
Moves the pointer back one page (20 lines) and displays the page. Repeating the command scrolls the pointer backward toward the top of the stack. |
/PI |
Previous Input |
Moves the pointer back and displays the previous 20 lines of input. |
/PO |
Previous Output |
Moves the pointer back and displays the previous 20 lines of output. |
/PC |
Previous Command |
Moves the pointer back to the previous FOCUS command issued and displays it and the lines following it. When you enter /PC repeatedly, each command appears above the previously displayed commands. The Session Monitor can display up to 20 lines at one time. |
/TOP |
Top of the Stack |
Moves the pointer to the top of the stack (at the oldest entry) and displays the first 20 lines of the stack. |
/LN [n|1] |
Line Command |
The effect of /LN n varies depending on your previous Session Monitor command:
Note: FOCUS does not recognize the /LN command unless you first issue another Session Monitor display command. |
Consider the following terminal session:
SET SM = ON

DEFINE FILE CAR
DCNEW/D10.2 = DEALER_COST * 5;
RCNEW/D10.2 = RETAIL_COST * 5;
END
>
