Card 9 introduces the ENTRY and NAME cards to the linkage editor to indicate the main entry point and the name of the program. Card 10 specifies the entry output data set for the link edit step which is the complete program. This is the data set where you store the LCRAND permanently. It is a partitioned data set which is used as a program library. You can use an existing one or create a new one. After the LCRAND is created, execute it in the following manner. Card Column 1 // EXEC LCRAND //STEPLIB DD DSN=D00ll271.SEQ.LOAD, // DISP=OLD //FTO6F001 DD SYSOUT=A //FT07F001 DD SYSOUT=B //GTO5FO01 DD * BEGIN ROWS [Row data] EIJD MLATRIX [Matrix data] EliD RHS RHS data] END SOLVE EXIT /*
