Beta 10: Substring out of range in MID$

[DavidN]

There's a slight problem with the code that corrects Mid$ expressions that would go out of range, in CEvents.m, expSys_MID. (For example: Mid$("Notenoughletters", 6, 999)) The code looks like it's trying to prevent the length parameter of Mid$ reading past the end of the string, but ends up with a negative length instead, which causes the same problem.

I think that the issue is just a missing "return" after the check for length being below or equal to 0. This works:

	if (start<0) start=0;
	if (start+len>l) len=l-start;
	if (len<=0) 
	{
		[getCurrentResult() forceString:@""];
		return;
	}

I just wanted to bump this back up again, as I exported anew with beta 15 and had to go in and change this again in CEvents.m (expSys_MID, expSys_LEFT, expSys_RIGHT)

My knowledge of Objective-C is rudimentary at best, but I will do what I can
