The RTNDATA statement allows a jBC program to return specific data to the RTNDATA clause of another program's EXECUTE statement.
expression may evaluate to any data type.
When a jBC program executes another jBC program using the EXECUTE statement it may specify a variable to pick up data in using the RTNDATA clause. The data picked up will be that specified by the executed program using the RTNDATA statement.
The data will be discarded if the program is not executed by an EXECUTE statement in another program.
