Return codes

00
User is allowed to access the resource.
04
Use ISFPARMS to determine authorization and allow access when ISFPARMS has no corresponding protection scheme. The SAF call is bypassed. This is the default return code if the user does not change the installation exit routine.
Note: This does not apply to the SERVER option on the SDSF command, which is protected by the ISFCMD.OPT.SERVER resource, as described in SDSF server.
08
User is not allowed to access the resource.
