Variable Assign Reference
Variable assign: domain plus username example
A Tcl command that separates the values of two session variables with a
backslash can provide the value for a domain and user name in this format
DOMAIN
\USERNAME
. Tcl expression in Variable Assign entry
A Tcl command in the
Custom Expression
pane provides the value for the custom variable, session.sbc_domainuser
.The custom expression
expr {[concat "[mcget {session.logon.last.domain}]\\[mcget
{session.logon.last.username}]"]}
obtains the values of the session variables
and concatenates them using a backslash as a separator. Both backslashes in the expression
are needed to work with Tcl backslash substitution rules.Variable assign: text assignment example
Variable assign configuration: a custom variable with a text value
Predefined session variable attributes
In the Variable Assign action, you can select Predefined Session Variable as the type
of variable to assign. Then you can select a predefined variable and assign a value to it. The
table lists the variables that you can select and provides the corresponding session variable
name and expected format for the session variable.
