Program Organization
The IVP (Installation Verification procedure) consists of two EXEC procedures: IVP and IVPX. Figure 6-2 shows the
structuring of the major routines of the IVP. Figure 6-3 relates the test sections
to the CP or CftS functions being exercised. INSTALLATION VERIFICATION PROCEDURE ROUTINE STRUCTURING IVP EXEC I IVPX EXEC Set up
