I'm trying to debug a product by changing everything back to its pre-customized state. Is there a way to dynamically remove/delete these, or would I need to remove them and IPL? 

Release:
Component: TSSMVS

 The TSS MODI FAC(XXX=NAME=USERxx) would only rename it back to the default...all the ACIDS that had the current facility name FAC(xxx) would now show USER25 instead. Also need to change the INITPGM back to *** TSS MODI FAC(USER25=PGM=***)
