Syntax
RunVBScript ( strScript, "optTagReturnError" )
strScript
Script statement that must be executed by the function.
optTagReturnError
Name of the tag that will receive the error (if any) generated by the statement (e.g., "Division by
zero"). The tag name must be configured between double-quotes and it must be a String tag.

Expression
RunVBScript("MsgBox(Time)") // Executes the MsgBox function from VBScript and displays the current time.
RunVBScript(TagStatement) // Executes the statement configured in the value of the string tag
TagStatement.
RunVBScript("$TagC=$TagA/$TagB", "TagError") // Writes in TagC the result of TagA divided
by TagB. The error generated by the operation (if any) is written to the string tag TagError (e.g., "Division by zero").
Tip: This function is useful to execute VBScript statements from interfaces that support the builtin
language only (e.g., Scheduler groups). You can also call VBSCript functions created in the Global
Procedures.
Note: The runtime station must support the VBScript statements configured in this function in
order to execute them.
