The DI option activates the one-line assembler/disassembler. All other options are invalid if DI is
selected. The contents of the specified memory location is disassembled and displayed and the
user prompted for an input with a question mark ( ? ). At this point the user has three options:
Enter <CR> – This closes the present location and continues with disassembly of the
next instruction. The instruction is unchanged.
Enter a new source instruction followed by <CR> – This actuates the assembler to
assemble the new instruction and generate a disassembly of the object code generated.
Enter <CR> – This closes the present location and exits the MM command.
If a new source line is entered (second option above), the present line is erased and replaced by
the new source line.
If an error is found during assembly, the caret symbol (^) appears below the suspect field
followed by an error message. The accessed location is redisplayed.
Refer to Chapter 4 for additional information about the assembler.
