The current date.
$date
A number in date format (YYYYMMDD). Cannot be reset by an application program.
The current date, as set in the operating system.
From the zim prompt:
out $date
This extracts the DATE from the TIMESTAMP and then prints the proper $DayName.
OUT $DayName($GetUTCDate($TimeSecs))
$transmitkey ObjectSyntax: $transmitkey
Return Value: Character string
Description:
The $transmitkey object captures the name of the last EXIT or TRANSMIT key pressed during form input operations. This object is essential for managing form navigation and submission, especially when custom key bindings are involved.
FORM SET or WINDOW SET ACCELERATOR commands.FORM INPUT if any “required” fields are empty.FORM INPUT to terminate.$transmitkey will be set to an empty string ("").$transmitkey:$transmitkey object can be reset at any time to clear its value. This is useful for ensuring that the object accurately reflects the most recent key press.To define EXIT and TRANSMIT keys, you use the FORM SET or WINDOW SET ACCELERATOR commands. For example:
FORM SET ACCELERATOR EXIT F2
FORM SET ACCELERATOR TRANSMIT F1
In this example, the F2 key is set as the EXIT key, and the F1 key is set as the TRANSMIT key.
You can check the value of $transmitkey to determine which key was pressed and take appropriate actions. For example:
IF $transmitkey = "F1" THEN
// Handle the F1 key press (TRANSMIT)
CALL ProcessFormSubmission()
ELSE IF $transmitkey = "F2" THEN
// Handle the F2 key press (EXIT)
CALL CancelFormInput()
ENDIF
In this example, different actions are taken based on whether the F1 or F2 key was pressed.
Imagine a form with several required fields. If the user presses the TRANSMIT key (F1) while in a modified transmit field, the form will attempt to submit. If any required fields are still empty, $transmitkey will be set to an empty string, indicating that the submission was not successful.
FORM SET ACCELERATOR TRANSMIT F1
FORM SET ACCELERATOR EXIT F2
// User presses F1 while in a modified transmit field
IF $transmitkey = "F1" THEN
IF AllRequiredFieldsFilled() THEN
CALL SubmitForm()
ELSE
$transmitkey = "" // Reset because required fields are empty
ENDIF
ENDIF
This ensures that the form submission logic is robust and handles incomplete data appropriately.
Traces the execution of explicit transaction commands.
SET TRANSACTION FLOW ON|OFF
The execution of explicit transactions (implemented using TRANSACTION, ENDTRANSACTION, and QUITTRANSACTION commands) is traced through the display of special messages, even in single-user systems.
Implicit transactions are not traced.
The logical width of the current window in columns.
$window pswidth
A number. Cannot be reset by an application program.
The logical width of the current window in character columns.
The $WindowPSWidth function is reset when the current window changes.
The logical height of the current window in rows.
$windowpsheight
A number. Cannot be reset by an application program.
The logical height of the current window in character rows.
The $WindowPSHeight function is reset when the current window changes.
Controls the use of a pointing device in Zim for Windows.
SET MOUSE ON|OFF
The MOUSE option is set ON by default.
When MOUSE is ON, the use of a pointing device is enabled for the client area of Zim windows. The application can then respond to mouse-button accelerators that occur while the focus is in a window.
The SET MOUSE command has no effect on standard windows. In such windows, it is assumed that a pointing device is active at all times, when available.

Indicates if the application user has pressed the “break” key.
$breakflag
Binary. Can be reset by an application program.
At the start of an application session, $BreakFlag is set to “0” ($False). Set to “1” ($True) if the application user presses the “break” key. The application program must reset the variable to “0” ($False) to be able to detect subsequent user interrupts.
Controls the use of the escape character in quoted character strings.
SET ESCAPECHAR ON|OFF
The ESCAPECHAR option is ON by default.
When ESCAPECHAR is ON, the backslash is treated as the escape character inside quoted character strings. Setting ESCAPECHAR to OFF causes the backslash to be treated as data. The OFF setting is particularly useful in operating environments where the backslash character is used as the path separator character.

Moves the current member pointer to the first member in a result set.
TOP [setname]
| setname | The name of a result set. If setname is omitted, the current set is used. |
The TOP command moves the current member pointer to the first record in the current set.
In a template program, indicates that the next line is to be joined to the current line at the output destination.
linestart «$ linecontinue »
where
| linestart | any portion, from the beginning, of an output line |
| linecontinue | the remaining portion(s) of the same output line |
In a template program, the dollar sign ($) indicates that the next line is to be joined to the current line at the output destination.
Normally, each physical line in a template is sent as a separate line to the current output destination. To cause successive physical lines in a template to be joined into one line in the output, end the appropriate lines in the template with the dollar sign ($).
If a line must end with a dollar sign for some other reason, ask the software to interpret the dollar sign by placing a backslash ( – Escape) preceding the dollar sign.
