Oracle Tuxedo Application Runtime for Batch provides a set of high-level functions that simplify script syntax enabling more readable and more easily maintainable Korn shell scripts.

Using these functions ensures consistent services; when used together, execution of one function can be conditional on the value of the return code produced by a preceding function.

A function is generally called directly from a Korn shell script resulting from JCL conversion.

Oracle Tuxedo Application Runtime for Batch normalizes Korn shell script formats by proposing a script model where the different execution phases of a job are clearly identified.
