Jump()

void formula::FormulaTokenIterator::Jump	(	short	nStart,
		short	nNext,
		short	nStop = SHRT_MAX
	)

Jump or subroutine call.

The nPC counts after a Push() are -1.

Program counter values will be incremented before code is executed => positions are to be passed with -1 offset.

Parameters

nStart	Start on code at position nStart+1 (yes, pass with offset -1)
nNext	After subroutine continue with instruction at position nNext+1
nStop	Stop before reaching code at position nStop. If not specified the default is to either run the entire code, or to stop if an ocSep or ocClose is encountered, which are only present in ocIf or ocChoose jumps.
