There is one case in which there might be problems. Looking at:
//MYFILE DD DSN=&SYSNAME,DISP=(,PASS),UNIT=SYSDA WIth SYSSYM set to DISALLOW, this will create a valid temporary dataset(JCL reference says that you should use a double ampersand but a singe works fine). WIth SYSSYM set to ALLOW, this will create a dataset that is called whatever your SYSNAME is. Other symbols will produce other strange names Mike On Mon, Jan 16, 2017 at 6:28 PM Jesse 1 Robinson <jesse1.robin...@sce.com> wrote: > I can't see any generic reason not to enable system symbols, but like many > changes that IBM has introduced over the years, it could have a deleterious > effect in particular cases.
