Multiplies one value by another.
[expression1]*expression2
The asterisk (*) multiplies the expression on the left by the expression on the right.
| expression1 | a number or expression that evaluates to a number |
| expression2 | a number or expression that evaluates to a number |
Arithmetic operators indicate the sign of a number or perform arithmetic operations (addition, subtraction, multiplication, division, exponentiation).

The highest error severity level generated during the application session.
$maxerrlevel
A number (0 to 4). Can be reset by an application program.
| Value | Meaning |
| 0 | No error. |
| 1 | Information message. |
| 2 | Warning. |
| 3 | User error. |
| 4 | System error. |
The highest error severity level encountered to the current point in the application session.
Calculates the arctangent of a number.
$atan(number)| number | a number, or an expression that evaluates to a number |
Number, with the same number of decimal places as number.
Use $atan to calculate the arctangent (in radians) of a number. The value returned by this function has the same number of decimal places as number.
let vAngle[1] = $atan(0.500)
The preceding command sets the first element of array variable vAngle to 0.464.
The location of focus in a window when an event occurs.
$cursorrow
A number which is the row location for focus of the current window at the time of an event. Can be reset by an application program.
The number of the character row where focus was located within the current window at the time of an event . If focus is on an entry field, $CursorRow gives the position of the text cursor.
To output the row and column position of focus in window wMain when an event occurs:
window open wMain form open Form1 form display input output $cursorrow $cursorcol
Sets up the access to the remote application.
DDEConnect ( out tErrCode,
out tServ,
in dde_app,
in dde_topic)
| tErrCode | A returned error code. It must be a longint. |
| tServ | The returned connection handle. It also must be a longint. |
| dde_app | A string containing the application name. |
| dde_topic | A string containing the topic name. |
The procedure is supplied with the application name and topic name (usually the document name). DDEConnect assigns a connect handle to the “tServ” variable to be used in subsequent commands. DDEConnect is compiled.
The filename is ddeconn.pgm.
For example, given that DDE_Err and hServ are of type longint:
DDEConnect (DDE_Err, hServ, ‘excel’, ‘sheet1’)
starts a conversation with Microsoft EXCEL. The topic of the conversation is the spreadsheet ‘sheet1’. In this case, EXCEL must be started and ‘sheet1’ opened beforehand.
Prints a text or bitmap file.
$fileprint(filename[,filetype])
| filename | a character string or an expression that evaluates to a character string |
| filetype | a number that determines if the file is a text file (0) or a bitmap file (1) |
The $fileprint function returns “1” ($True) if no errors were detected before the print job was submitted. Otherwise, it returns “0” ($False).
Bitmap printing is available only in the Windows environment.
Prints the contents of a window or application document.
PRINT name
| name | The name of a window (GUI environments only) or application document. |
If name identifies a window, the window must be open and activated. The visible portion of the window is sent to the current output destination as a bitmap. Bitmap output can be produced in a GUI environment only.
If name identifies an application document, the application document is sent to the current output destination as a text file.
Divides one value by another.
[expression1]/expression2
The oblique (or slash, /) is the division operator. It divides the expression on the left by the expression on the right.
| expression1 | a number or expression that evaluates to a number |
| expression2 | a number or expression that evaluates to a number |
Arithmetic operators indicate the sign of a number or perform arithmetic operations (addition, subtraction, multiplication, division, exponentiation).

The application user’s Zim group identifier.
$zgroupid
The group identifier of the user specified in the last successfully executed LOGIN command. Cannot be reset by an application program.
Upon successful execution of a LOGIN command, $ZGroupID is set to the specified user’s group identifier.
Although you can change the value of this variable, you cannot change the effect of the LOGIN command. The current user continues to be treated according to the GroupID and UserID associated with the UserName given in the last LOGIN command.
When you call up any Zim system (full, Runtime, etc.), the software automatically attempts to log you in as a user called ZIM.
The location of focus in a window when an event occurs.
$cursorcol
A number which is the column location for focus of the current window at the time of an event. Can be reset by an application program.
The number of the character column where focus was located within the current window at the time of an event. If focus is on an entry field, $CursorCol gives the position of the text cursor.
To output the row and column position of focus in the current window when an event occurs:
window open wMain form open Form1 form display input output $cursorrow $cursorcol
