The trace function is a logic debugging aid used with Pronto Script console, intended to offer more than System.print. It has 4 optional user definable arguments:

function = trace (location, variables, traceDecision, traceType)

• trace () prints the function that called trace
• trace ("here") also prints user supplied location information
• trace (variables), where variables is an array of variable names prints the content of the variables. Each name between quotes.
• trace ("locA", variables, 1) prints also line with variable types
• trace ("locB", variables, 2) prints only a line with variable types, below the location information (caller function + location)

Although it is a quite a large function (a.o. due to the various possibilities and checking), it is easy to use.
