TSOLIB CommandOperation: (1) Allocate a third data set my.load and specify the ddname aalib tobe associated with it, (2) activate ddname aalib with the TSOLIB ACTIVATEcommand, and (3) use the TSOLIB DISPLAY command to display the currentlyactive and stacked ddnames.ALLOCATE FILE(aalib) DATASET(my.load)TSOLIB ACTIVATE FILE(aalib)TSOLIB DISPLAYIDY00022I Search order (by DDNAME) is:IDY00023I DDNAME = AALIBIDY00024I DDNAME = SYS00102 (Stacked)IDY00024I DDNAME = SYS00101 (Stacked)The previously activated ddname SYS00102 is temporarily deactivated and marked(Stacked) in addition to SYS00101. Ddname AALIB is the active library includedahead of the standard search order.Example 7: The use of the TSOLIB COND operandOperation: Based on “Example 6: The use of TSOLIB library stacking” on page364, try to activate ddname trylib with the COND operand.ALLOCATE FILE(trylib) DATASET(your.load)TSOLIB ACTIVATE FILE(trylib) CONDIDY00015I TSOLIB terminated. Load library already activeand COND keyword was specified..TSOLIB DISPLAYIDY00022I Search order (by DDNAME) is:IDY00023I DDNAME = AALIBIDY00024I DDNAME = SYS00102 (Stacked)IDY00024I DDNAME = SYS00101 (Stacked)The activate request is unsuccessful; the previous activation remains unchanged.Example 8: Reactivate a TSOLIB library from the stackOperation: Based on “Example 6: The use of TSOLIB library stacking” on page364, (or “Example 7: The use of the TSOLIB COND operand”) exclude the currentlyactive library AALIB and activate the last one stacked (SYS00102).TSOLIB DEACTIVATETSOLIB DISPLAYIDY00022I Search order (by DDNAME) is:IDY00023I DDNAME = SYS00102IDY00024I DDNAME = SYS00101 (Stacked)Example 9: The use of the TSOLIB QUIET operandOperation: (1) Activate a single data set ’aalib.load’, to which the systemassociates a ddname of SYS00100, (2) activate a concatenation of data sets, towhich the system associates a ddname of SYS00101, (3) and invoke a REXX execto show use of the QUIET operand when ISPF is active.The contents of the variables in the ISPF shared pool are then examined.
