#2590: Uninitialized variable in Perl code

 Reporter: Erik Schnetter
   Status: new
Milestone: 
  Version: development version
     Type: bug
 Priority: minor
Component: Cactus

I receive this error from the CST stage:

```
CST error in /Users/eschnett/Cactus/arrangements/CarpetX/CarpetX/interface.ccl (at 129)
  -> SYNTAX ERROR

Use of uninitialized value in concatenation (.) or string at /Users/eschnett/Cactus/repos/flesh/lib/sbin/interface_parser.pl line 985.
```

for this code:

```
CCTK_REAL regrid_error TYPE=gf CENTERING={ccc TAGS='index={1 1 1}'
{
  regrid_error
} "Regridding condition"
```

The code is wrong \(it’s missing a closing brace\), but the error message should be better.
