I am writing an XFCN in Think C for a SuperCard application. When I first wrote it I used no arguments, but as I got the code to work right I added arguments one at a time. I got several generations of the program to run just fine for the first 4 arguments, but when I added the fifth argument, the program stopped working right. The fifth argument seems to be reaching the XFCN just fine, because I print out its value in the message box using SendCardMessage(). Following that, the program is supposed to draw some lines into a window using several LineTo() calls. When the fifth argument is present the lines never appear, but when it's not present the lines do appear. Except for the call to SendCardMessage(), the fifth argument is not used anywhere in the program. Actually, even when I take out the SendCardMessage() call, I get the same results. I have tested this several times. No fifth arg, it works fine; add the fifth arg, it stops working. I thought XCMDs and XFCNs were supposed to handle up to 16 args or so. What's up, anybody know?
