Whenever the 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. High Level Assembler messages describes the abnormal termination messages. The messages give enough information to enable you (1) to correct the error and reassemble your program, or (2) to determine that the error is an assembler malfunction.
