Design and implement an assembly for SIC$/$XE

The test data look like Figure $2\mathrm{.}5.$ and are generated by

MS Notepad.

The possible OPCODE in the test data contains all the

OPCODEs which appear in Figure $2\mathrm{.}5.$ They include

STL$,$ LDB$,$ LDA, COMP,...

The assembly directives include all those appear in Figure

$2\mathrm{.}5.,$ e$.$g$.,$ START, $+,$ BASE, BYTE, RESW, RESB,

END, $....$

The name of labels are not allowed to be the same as

OPCODEs or assembly directives.

The format of the object program generated by your

assembly should conform to Figure $2\mathrm{.}8.$
