The code sets the value to 1 and then increments the value some number of times. Nowhere in the code is the value reset or decremented. How does that allow any condition other than the test will always be true? What difference does it make whether it is the first test or the 100th? </end extract> The answer can Indeed be no. I commented only on what was posted. The first time the if statement, the first within the scope of the for, is executed, the value of c is 1. Thereafter, it can have any value in the supported C-language int interval, for this implementation -2147483648 <= c <= +2147483647, The C language imposes no FORTRAN-II-like restriction on the value of a for-statement index variable. It can be reset within the scope of that for. I thus meant just what I said. If "retired mainframer" reads CAPL---where this issue is discussed explicitly---with more care and thus acquires a better grasp of C syntax he may well be in a position to make more informed comments. If not, not.
