Explanation:

1. Initialization:

   • local result = ''

2. Pressure Range Check:

   • Checks if model['PressureRange'] is not null/empty and assigns result.

3. Temperature Range Check:

   • Checks if model['TemperatureRange'] is not null/empty and assigns result.

4. Range Condition:

   • Checks if result is still empty, and if model['Smax'] and model['Smin'] are not equal and both non-zero, assigns a range to result.

5. Result Suffix for VUnits:

   • Appends VUnits name to result if not null/empty and not '-'.

6. Result Suffix for SUnits:

   • Appends SUnits name to result if VUnits is null/empty and SUnits is not null/empty and not '-'.

Note:

• Lua uses the ~= operator for inequality, unlike != in some other languages.
• Lua uses the : syntax for calling methods of objects (e.g., ScriptHelpers:IsNullOrEmpty).
• The code is written in a compact and readable format consistent with Lua best practices.
