In the following example, a program establishes addressability to a data space named TEMP. Input to the ALESERV macro is the STOKEN that the DSPSERV macro returned. ALESERV places an entry on the DU-AL and returns the ALET for the data space.

         ALESERV ADD,STOKEN=DSPCSTKN,ALET=DSPCALET,AL=WORKUNIT
         .
DSPCSTKN DS   CL8                      DATA SPACE STOKEN
DSPCALET DS   F                        DATA SPACE ALET
