Suppose that ALPHA is an array of 100 words, as defined in Fig. 1.5(a). Write a sequence of instructions for SIC to set all 100 elements of the array to 0.
Solution
| Line Number(ac) | Code | Description |
| 1 | LDA ZERO | |
| 2 | STA INDEX | |
| 3 | LOOP LDX INDEX | |
| 4 | LDA ZERO | |
| 5 | STA ALPHA, X | |
| 6 | LDA INDEX | |
| 7 | ADD THREE | |
| 8 | STA INDEX | |
| 9 | COMP K300 | |
| 10 | TIX TWENTY | |
| 11 | JLT LOOP | |
| 12 | INDEX RESW 1 | |
| 13 | ALPHA RESW 100 | |
| 14 | ZERO WORD 0 | |
| 15 | K300 WORD 100 | |
| 16 | THREE WORD 3 |
