Detect number entry on HP-35s?

For instance there is no LBL W in line 001 (which is required for branching to line numbers) and I also wonder what line 005...011 will do. At line 005 the value in X always is 1.001, so the following three lines will always evaluate to 1000 and the display is [1000, 1]. Is this how the program is supposed to work? What is this [1000, 1] supposed to mean? Due to the "1E3 x" in line 007-008, LastX always is 1000, and so is the first value displayed within the square brackets.

The code was thrown together last night and isn't complete (nor debugged).

Here was the thought process:
1. User enters the starting register number on the stack
2. Execute Program W
3. Flash array [column,row] (using two stack registers as counters)
4. Input value in variable A
5. Store in (I), beginning with starting register.
6. Increment counters and indirect register number
7. Go to step 3 until first column is filled
8. Start next column (Flag 0)
9. Exit program
