DB2 Server for VSE & VM: Interactive SQL Guide and Reference

Entering CP Commands

You can enter CP commands in three ways:

• A CP command can be typed at any time during ISQL processing by prefixing the command with #CP. This procedure immediately interrupts the current ISQL processing, enters CMS subset mode and performs the designated CP command, and then returns to ISQL when the command is complete.
• You can press PA1 at any time. CP READ appears in the status area and you can type any CP commands.

  If you are running with CP SET RUN ON, control automatically returns to ISQL after each CP command is executed. ISQL resumes processing from the point of interruption. If you are running with CP SET RUN OFF, you must type a B or begin on the input line and press ENTER to resume processing in ISQL.

  The SET FULLSCREEN ON command cancels the interrupt action of PA1. Suspending the full-screen option or turning it off does not reset PA1 to the original interrupt setting. If PA1 does not interrupt ISQL, you can reestablish it as an interrupt key with the following command:

     #cp terminal brkkey pa1
  

• While in CMS subset mode, you can type CP commands (with or without the CP prefix) in the same manner as that described above for CMS commands.

As a DB2 Server for VM user, you probably use CP commands only when you want to change printer spooling or routing characteristics, or change PF key definitions.
