FCONTROL ACTMSG

Purpose

The FCONTROL ACTMSG subcommand specifies the number of action messages (line type CPAMSG) that are to be left pending at the top of the screen while the virtual machine running Performance Toolkit is logged on to a display terminal. Action messages will be scrolled only while their number exceeds the value defined with the ACTMSG subcommand. ACTMSG is initialized to a value of ten.

Parameters

n1
Specifies the number of action messages that are not to be scrolled. Minimum is 0 and the maximum is 99 (will keep all action messages on any screen).
Query
Inserts and displays the current value of ACTMSG on the command line. QUERY is the default.

Usage

  1. The ACTMSG setting will be ignored while the virtual machine running Performance Toolkit is in disconnected state if the logical display would otherwise become locked.

    This change in the scrolling logic is implemented in order to prevent a lock-up of the (disconnected) logical display which could lead to an abend due to storage constraints when none of the new output lines can be unstacked and inserted into the basic mode display.
