throw

Scripts > Class elements and c++ instructions > Interpreted C++ instructions > throw

With an instruction of the kind:

throw CTT_Error("error message");

a TETRA program can be canceled. An arbitrary text or a string variable can be passed as message. In the C++ jargon for this statement is said, that the exception "CTT_Error" is thrown. Inside of the TextTransformer, the text will be shown in the log window.

User defined error message: error message.

Remark: Such a break is executed in the term production of the calculator example to prevent a division by null.

An alternative to the throw command is the function GenError.

You can force a stop of a program also, if the interpreter is deactivated. For this the key word EXIT is defined.
