In COBOL pseudocode, DFH0SAL1 creates and starts an instance
of the Sale business transaction. The initial request to start a Sale
business transaction is handled by the DFH0SAL0 and DFH0SAL1 programs.
When a terminal user selects the Sale menu option
by typing SALM, the menu program DFH0SAL0 links
to the DFH0SAL1 program to service the request. The DFH0SAL1 program
establishes a unique reference for this instance of the Sale business
transaction and starts it.
