What should the name of a parameter be surrounded by when it is defined?

What should the name of a parameter be surrounded by when it is defined?

• A. Pipes only: |ParameterName|
• B. Pipes and exclamation marks: |!ParameterName!|
• C. "Exclamation marks only: !ParameterNameExample!"
• D. Asterisks only: *ParameterNameExample*

Answer: (B)

In OneStream, parameter references are written as a token that tells the system to substitute the actual value at run time. That token uses both pipes and exclamation marks around the name, so the engine can identify and evaluate it correctly. The standard form is |!ParameterName!|, where the pipes mark the token boundary and the exclamation marks denote that the inside is a parameter reference to be replaced with its value. Using only pipes would leave the parameter not clearly marked as a dynamic reference, and using only exclamation marks would lack the required token boundary, so the system wouldn’t recognize it as a proper parameter token. The asterisks are not part of the parameter syntax either. For example, if the parameter is named RevenueForecast, the token |!RevenueForecast!| will be replaced with its actual value during calculation.
