Line 16:
Indicate if your language supports ''user defined'' type conversion definitions and give an example of such a definition. (E.g. define an ''implicit type conversion'' from '''real''' to '''complex''' numbers, or from '''char''' to an array of '''char''' of length 1.)

There is no implicit type conversion in the "modern" sense. However, you are free to interpret any bit pattern to mean whatever you want, when you want. A few language constructs help with this.
The X and Y registers can be used as loop counters, or as an indexed offset into memory. It's very common for both to be true in the same procedure.
<lang 6502asm>memcpy:
LDA ($00),y ;load from (the address stored at $0000) + y
STA ($02),y ;write to (the address stored at $0002) + y
iny
bne memcpy ;loop until y = 0
rts</lang>
Any 16-bit value stored at a pair of consecutive zero-page memory addresses can be treated as a pointer to memory. The above example demonstrated this with the use of <code>($nn),y</code>.
