UPDATE

Syntax:

       Then: update

Note: Available on automatic processing tables only.

Version Ref:  3.x

Description:

The UPDATE command puts the user into update mode automatically and/or conditionally from automatic processing. In effect, it presses "U" for the user.

Examples:

Since automatic processing happens at least twice, it is important to test whether or not the user is already in update mode to prevent "updating" again and again and again.... Use the following combination of commands to prevent the user from looping through the automatic processing forever.

On the automatic processing table:

         If: q eq ""
       Then: q(1,,g)="1"; update
         If: q eq "2"
       Then: q=""

Put the following at the bottom of the INPUT processing table:

       Then: q= "2"
