J.FREE - free the allocated JOUT PAT.

Usage:

j.free();

Description:

In order to do JOUT I/O, J.READ and J.WRITE allocate a private PAT in TSS. Normally, this PAT is allocated once and deallocated in wrapup. However, since there is only room for one allocated PAT in the UST, it is important that it be deallocated before calling another subsystem, in case that subsystem needs to allocate a JOUT PAT for its own use. Thus before calling another subsystem, a program that calls J.READ or J.WRITE must call J.FREE to free the PAT. If J.READ or J.WRITE are called again, they will allocate a new PAT.
