The executeIOScript method of the Process class executes a Jade script passing parameters as io (input-output) and provides a wrapper method for calling the createTransientMethod, executeTransientIOMethod, and deleteTransientMethod methods to compile and execute Jade method source code.

This method returns the result value returned by the executed method. The method is executed as part of the current Jade process and any references to system variables (for example, app) reference those for the application that is currently running.

The executeIOScript method parameters are listed in the following table.

Parameter	Description
methodName	The name of the method to be created. For non‑Workspace methods, this parameter must match the method name specified in the signature in the source code.
schemaType	The owner type, or owner root type, of the method (that is, the type of the method receiver) and it is the type of the self system variable.
schema	The schema against which the method is to be compiled and which is searched when resolving the names of classes referenced in the method.
sourceCode	The method source code to be compiled.
isWorkspaceMethod	Specifies whether the source code is in Jade Workspace format (that is, it has no method signature). Jade Workspace format transient methods cannot update the receiver directly.
returnType	Specifies the type of the result value returned by Workspace methods. For non-Workspace methods, this parameter is not used and the return type is specified in the method signature in the source code.
errorCode	The error code returned by the compiler. A value of zero (0) indicates that the method was compiled successfully.
errorPosition	The position of the error in the source code. Note that the first character of the source code has a position of zero (0).
errorLength	The length in characters of the error in the source code.
receiver	The receiving object or primitive type, defined as an io parameter to allow it to be updated by an updating method specified in the methodName parameter.
params	Maps to a variable list of zero or more parameters of any type that are to be passed to the method that is executed. This parameter is defined as io to allow the passing and updating of parameters defined as io in the signature of the method specified in the methodName parameter. (The ParamListType pseudo type can be used only as a formal parameter in a method signature. You cannot define a local variable with a type of ParamListType.)

For details about the ParamListType pseudo type specified in the last formal parameter (params), see "ParamListType" under "Pseudo Types", in Chapter 1 of the Developer's Reference. See also "Passing Variable Parameters to Methods" under "Jade Language Syntax", in Chapter 1 of the Developer's Reference. If the source code does not compile successfully, the error parameters return compiler information that indicates the cause of the error.
