All Implemented Interfaces:

Serializable

public class TclExec

extends Instruction

Execute an external command. Executes string as a Tcl command in the host system, producing either a true value and a data value (if a data value is the result of the script) or a false value with no data value if the result of the script is an empty string. All other script results cause exceptions out to the hosting simulation environment. This instruction is intended for use in the implementation of source nodes, and should not be generated from any ordinary Yellow or Green source code, and the meaning of the string argument is defined by the handling host environment.

string data true	(with datavalue-string result)
string false	(with empty-string result)
