in Figure A-4, represents the execution of multiple actions,
i.e., the execution of a procedure.
<1> First Procedure. Procedure sequence structures are
modeled using rectangles with double-line borders on
two sides. They are executed one at a time in order,

but unlike simple sequence structures, a separate
process chart is required for each procedure
sequence structure. Use a second process chart to
execute the first procedure. After finishing the first
procedure, proceed to <2>.

Selection Structure. This handbook uses two types of
selection structures: simple selection and case. The two
structures are described in the following paragraphs.
A.4.1
Simple Selection Structure. The simple selection
structure, shown in Figure A-5, asks a question, in the form of a
conditional, that requires a yes or no action. A specific action
is taken for a yes response and another action is taken for a no
response.
