Re: [PATCH 0/1] MR4615: vbscript: For for loop coerce right bound string to real.

[Jacek Caban (＠jacek)]

It seems to me that we should convert step to a number earlier. I tried a simple test:

```
dim x
for x = 1 to 2 step "a"
    call ok(false, "in for..to, expected an earlier error")
next
```

On Windows it throws type error earlier, before the first step. To implement that, I guess we could have a new opcode converting value to a number and use that instead of OP_val in `compile_forto_statement`.
