>>-HISTory-----------------------------------------------------><

IDF maintains a history of the last 1,023 instructions executed, and the order in which they were executed. HISTORY is only valid when the PATH or PATHFILE option is ON.

When the HISTORY command is executed, an arrow is placed beside the last instruction that was executed. This arrow appears on the right side of the screen, just to the left of the instruction count in the first Disassembly window. The arrow is only displayed against the disassembled assembler code. If the Disassembly window is displaying source code, then you need to issue the SHOW DISASM command to see the arrow.

While the HISTORY arrow is shown in the window, the PREVIOUS and NEXT commands do not scroll the open windows on the screen. Instead, they move the arrow to the previously executed instruction or to the following instruction.

The display remains in this state until a DUMP, DISASM, RUN, or STEP command is executed.

This lets you review the series of instructions that lead to an incorrect result.
