Well, we ran headlong into that very problem ourselves. What is going on is that the Encore C compiler puts variables into registers (making the 'register' declaration somewhat superflous). Upon longjmp, the contents of the registers are restored to what they were at the time of the call to setjmp and since your flag has been stuffed into a register, it is being reset. Declaring your flag variable as 'static', should solve your problem, though even that did not work with older versions of the compiler. -Clyde Hoover Shouter-To-Dead-Parrots @ Univ. of Texas Computation Center; Austin, Texas clyde@emx.utexas.edu; ...!cs.utexas.edu!ut-emx!clyde Tip #268: Don't feel insecure or inferior!
