As ever, you use this free program at your own risk.
Feel free to use the free software on this site but please honor the copyright.
There are occasions where you need to compress, delete or rename a dataset that
shares it's name with a dataset currently in use by the operating system
(usually on a backup IPL volume). By using our ZAPVTOC facility you can
get around this restriction.
ZAPVTOC, as the name implies, will alter the FORMAT4 record in the VTOC
for the file therefore bypassing enqueue issue. Obviously this is a very powerful
tool and should not be used by anyone other than a fully experienced System
Programmer. It can be protected using the system security software
(RACF™, ACF2™, etc).
As shipped, ZAPVTOC will check the users access to the dataset
SYS1.PARMLIB.
ZAPVTOC will cut an SMF record (by default a type 233 record) whenever it is used.
Due to the powerful nature of this tool we respectfully request that you
contact us to get a free copy.
ZAPVTOC comes with a REXX exec (VU) which can be used as an
ISPF 3.4 line command.
