Parser not capturing PF fields if there are no positions.

DDS parser is not capturing the fields when there are no positions for PF file. Below is a sample PF file with no positions,

```
A R PF1
A EMPID 10A TEXT('User ID')
A EMPNAME 50A TEXT('User Name')
A EMPDOB L DATFMT(*ISO) TEXT('Date of Birth')
A EMPNUMBER 10A TEXT('Mobile Number')
```

We should be able to capture the fields when there is a name for a field. I am working on it and will raise a PR soon.
