Multiple variables of same name with different prefixes not treated as separate variables

In QB4.5 the following code:
```basic
a& = 50000
a% = 32000
```
results in this output:
```
50000
32000
```
Whereas in QBJS the same code results in the following:
```
32000
32000
```
because QBJS is reassigning the variable, rather that treating it as a separate variable.
