# System Parameters

'IT' | Trace IF Condition

## Description

Setting the 'IT' parameter to On enables the addition of trace lines to both any active trace file (or console) and the Trace Window consisting of any IF condition evaluated and its result (True or False).

The output consists of "IF: xxxxxx ! True/False" immediately after the trace line output. In the Trace Window, the output is displayed with a pale red or green background to clearly indicate if the results are True (green) or False (red).

An option for turning the 'IT' parameter On or Off is provided in the Trace Window.

#### Note:
The IF output is shown only if the line is displayed on the trace (i.e. no display on protected programs).

(The 'IT' system parameter was added in PxPlus 2018.)
