• Utility control statements do not support temporary data set names that begin with an ampersand. You can code the complete name generated for the data set by the system (for example, DSNAME=SYS95296.T000051.RP001.JOBTEMP.TEMPMOD). For utilities where you identify data sets only on DD statements or the dynamic allocation equivalent, you can use a temporary data set name that begins with an ampersand.
• The utility programs described in this publication do not normally support VSAM data sets. For certain exceptions, refer to the various program descriptions.
• You identify ASCII tape data sets with LABEL=(,AL) or OPTCD=Q.

  The utilities that read or write binary (non-text) data on tape do not support ASCII tapes. This is because ASCII tapes require all data to be text. The utilities that do not support ASCII tapes include IEBCOPY, IEHMOVE, and IFHSTATR.
