Helper macros

setf (int Mode, int Flag)

Identical to Mode |= (Flag). Sets a Flag or flag combination in the variable Mode without affecting the other flags. For instance, setf(TradeMode,TR_PHANTOM) sets the TR_PHANTOM flag for the TradeMode variable.

resf (int Mode, int Flag)

Identical to Mode &= ~(Flag). Resets a Flag or flag combination in the variable Mode.

isf (int Mode, int Flag): int

Identical to (Mode&(Flag)). Evaluates to nonzero when the a Flag in the Mode variable is set. For instance, if(isf(TrainMode,PEAK)) ... checks if the PEAK flag is set in the TrainMode variable.

swap (var a, var b)

Macro that sets a to b and b to a.

Remarks

setf(a,b) is equivalent to a |= b; and resf(a,b) is equivalent to a &= ~b.
The difference of setf(Mode,Flag) and Mode = Flag is that the latter resets all other flags in Mode.
After if, use winged brackets for swap, f.i. if(some_condition) { swap(A,B); }.
The macros are defined in variables.h.

Example:

function run()
{
  setf(TrainMode,PEAK);
  setf(Detrend,SHUFFLE); 
  ...
}
