Whenever an assembly cannot complete, High Level Assembler provides a message and, in some cases, a specially formatted dump for diagnostic information. This might indicate an assembler malfunction or it might indicate a programmer error. The statement causing the error is identified and, if possible, the assembly listing up to the point of the error is printed. The messages in this book give enough information to enable you to correct the error and reassemble your program, or to determine that the error is an assembler malfunction.

If SYSPRINT or SYSLST (z/VSE) is unavailable, the assembler uses the macro WTO with a route code of 11 and a descriptor code of 7, or the system defaults, to output the messages.
