Example

gnSessionID is int
gnSessionID = mlInitialize()

IF gnSessionID = -1 THEN
Error(ErrorInfo(errFullDetails))
END

// Code of BTN_ListVariables button
sVarList is string = mlListVariable(gnSessionID)

EDT_Result = sVarList

gnSessionID is int
gnSessionID = mlInitialize()

IF gnSessionID = -1 THEN
Error(ErrorInfo(errFullDetails))
END

// Code of BTN_Create_Variables button
aParameter is array of 1 real = [4]
aResult is array of 1 by 1 real = [[123]]

IF NOT mlSetVariable(gnSessionID, "i", aParameter) THEN
Error("Failure writing the variable")
RETURN
END

sCodeToRun is string = "myRoot = sqrt(i)"
EDT_Result = mlExecute(gnSessionID, sCodeToRun)

aResult = mlGetVariable(gnSessionID, "myRoot")
IF ErrorOccurred THEN
Trace("Error: " + ErrorInfo())
END

Trace("Root = " + aResult[1,1])

Trace("List of variables before deletion: " + mlListVariable(gnSessionID))

mlDeleteVariable(gnSessionID, "i")
mlDeleteVariable(gnSessionID, "myRoot")

Trace("List of variables after deletion: " + mlListVariable(gnSessionID))
