= GetBelowZero =
Get below zero status.

{{{
bool GetBelowZero(int nScale = process_scale)
}}}

== Parameters ==

 * nScale - scale number

== Return Value ==

 * Returns true if the specified scale weight is below zero or false if the weight is zero or above.

== Remarks ==

The value returned is from an internal memory buffer from the last MnBdRead that received a weight for the specified scale. An application program should be structured properly for this data to be updated when needed. 

== Examples ==

{{{
if(GetBelowZero())
{
    DisplayText(20, 20, "Below Zero");
}
}}}

{{{
if(GetBelowZero(1))
{
    DisplayText(20, 20, "Below Zero");
}
}}}
