Figure 38. RVA Status before Loading Any Data

We used the following job stream (which uses DITTO to create six files) to load

the data onto the RVA:

// JOB BUILD DATA ON PATEV1 (80E)

// OPTION NODUMP

// ASSGN SYS005,DISK,VOL=PATEV1,SHR

// DLBL OUTPUT,′EXPIRED.DSF.DATA.FILE′,1998/300,SD,DSF

// EXTENT SYS005,PATEV1,1,1,4035,1500

// UPSI 1

// LOG

* DISPLAY RVA DATA FOR PATEV1 (80E) -- BEFORE DATA LOAD.

// NOLOG

// EXEC DTRIATTN,PARM=′IXFP REPORT,PATEV1′

// LOG

* BUILD EXPIRED, DATA-SECURED FILE ON 80E

* 17,000 RECORDS, 4,000 BYTES LONG, RANDOM FILL CHARACTER
