void	IfInstruction.process(ProgramEnvironment env) This instruction will evaluate it's criteria, if it evaluates to true, it will push the corresponding sub Program on to the top of the program stack, and break from the loop.
void	ExecSqlInstruction.process(ProgramEnvironment env) Processing this instruction executes the ProcessorPlan for the command on the CommandStatement of the update procedure language.
void	ExecDynamicSqlInstruction.process(ProgramEnvironment env) Processing this instruction executes the ProcessorPlan for the command on the CommandStatement of the update procedure language.
void	CreateCursorResultSetInstruction.process(ProgramEnvironment env) If the result set named rsName does not exist yet in the ProcessorEnvironment, then this instruction will define that result set.
void	AbstractAssignmentInstruction.process(ProgramEnvironment env) Updates the current variable context with a value for the Variable defined using a DeclareInstruction, the variable value is obtained by either processing a expression or a command(stored as a processplan).
