Using SLIP commands

Use a SLIP command only at the direction of the system programmer. You can enter a SLIP command:

On a console with MVS™ master authority.
On a TSO terminal in OPERATOR mode.
In a TSO CLIST.
In the CLIST, use the line continuation character at the end of each line and the END parameter at the end of the last line.
In an IEACMD00, COMMNDxx, or IEASLPxx parmlib member.
While you can enter a SLIP command in any of these members, IBM® recommends that you place your SLIP commands in IEASLPxx and enter a SET SLIP=xx command to activate the member. IEACMD00 and COMMNDxx require that a command be on a single line. Also, SLIP may process commands in IEACMD00 and COMMNDxx in any order, but processes commands in IEASLPxx in the order in which they appear.
The security FACILITY class entity IEASLIP.REFRESH is provided for using the REFBEFOR and REFAFTER keywords on the SLIP command. When the IEASLIP.REFRESH FACILITY class profile is defined, the SLIP command issuer must have UPDATE access to that profile to use the REFAFTER and REFBEFOR keywords.
