I am not sure that i can help you completely, but i have researched this
call quite thoroughly.
$514B is a call that finds the next _matching_ Variable in the VAT.
This means that there is input. Put $12,$00 into op1 with rst 20/10, then
xor a before you make the call. There is also $514F which finds a previous
var of type in OP1.
So, If you put $12,$00 into OP1, then call the $514B thing, the calc will
return the first program on the calc. If you call it again, then it will
return the second program in the VAT. Unless of course there isn't one.
Then it returns a carry flag. Take a look at the source to minishell on
ticalc.org. It should give you a fairly good sence of how to use it.
