Change between Classic and New Menus

Q:

After installing ISPF/VSAM utility I changed my profile to use 'classic' mode thru the 'OPTIONS' menu. How do you change it to the new menu drive panels from the 'classic' menus short of deleting 'IVUPROF' from the ISPPROF dataset?

A:

Enter TSO IVU OPTS from any TSO panel to invoke the Options panel to change your 'Classic Mode' setting.
