Hi Jürgen: I've been thinking again about this warning and I'm inclined to agree with it.
..MyProjects/GNUAPL/apl-svn/src/UserFunction.cc:1191:10: Comparison of constant 10 with expression of type 'Function_Line' is always true if (l < 10) ucs.append(UNI_ASCII_SPACE); These suggestions eliminate the Warning. In File APL_Types.hh enum Function_Line { Function_Retry = -2, // →'' in immediate execution Function_Line_0 = 0, Function_Line_1 = 1, Function_Line_MAX = 10 // << === My suggestion }; In UserFunction.cc:1191:10: if (l < Function_Line_MAX) ucs.append(UNI_ASCII_SPACE); // << === My suggestion
