The error severity level generated by the last command that returned an error severity level.
$lasterrlevel
A number (1 to 4). Can be reset by an application program.
The error severity level of the most recently executed command that returned an error severity level other than 0 (success).
| Value | Meaning |
| 1 | Information message |

Indicates the character set used by the application database.
$dbcharset
2 for ANSI or 3 for UTF-8, depending on the character set specified when the database was initialized. Cannot be reset by an application program.
When you initialize a new application database, the database (ZIMBOOT) administrative utility requires you to specify the character set to be used. Once the database has been initialized, the character set cannot be changed.
During an application session, the $DBCharSet system variable contains the name of the character set used by the current application database.
ANSI is a Zim constant with a value of 2, so you could use the following:
if $DBCharSet = ANSI ... endif
The name of a graphics software package.
$graphics
A character string. Can be reset by an application program.
Set by the application program to the name of a graphics program.
$Graphics can be set to the name of a graphics program of your choosing. The name should include the full disk path. The special file path indicator characters can be used.
The GRAPH command automatically calls up the program named in the $Graphics system variable.
When running ZimTC, the following code will simply copy the “xxx.zzz” to the client side without executing any further actions:
let $graphics = "" graph "xxx.zzz"
let $graphics = "c:chartappchart.exe"
Indicates the direction in which focus was moving when an event occurs.
$direction
A number (-1, 0, or +1.) Can be reset by an application program.
The direction of travel of focus when an event occurred.
| Value | Meaning |
| -1 | “Backward” direction. The focus was moving backward (with respect to the current TABORDER) when an event occurred. |
| 0 | No direction. The focus is not moving. |
| +1 | “Forward” direction. The focus was moving forward (with respect to the current TABORDER) when an event occurred. |
The number of records processed by the most recent set-processing command.
$membercount
A number. Can be reset by an application program.
The number of records processed by the most recent set-processing command.
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.
These system variables have been removed from the Zim syntax and are replaced by WINDOW STATUS.
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))
The elapsed number of seconds since 12:00 am, 1 January 1970.
$timesecs
A number. Cannot be reset by an application program.
The number of seconds that have elapsed since 12:00 am on 1 January 1970.
This variable is useful for measuring the number of seconds between two events.
