What is the correct statement to end the syntax for the ToCelsius function in PROC FCMP?

The correct statement to end the syntax for the ToCelsius function in PROC FCMP is ENDSUB. In the context of PROC FCMP, when defining a function, the ENDSUB statement marks the conclusion of the function's definition. This is consistent with the syntax and structure required for creating user-defined functions in this procedure.

Understanding the function creation in PROC FCMP is vital, as it allows users to define custom computational logic. ENDSUB specifically indicates the end of the function’s body, similar to how the BEGIN statement starts the function definition.

The other options, such as END and ENDFUNC or ENDFUNCTION, are not used in PROC FCMP and could create confusion since they may seem valid in different programming contexts but do not apply directly to the specific syntax required by PROC FCMP for terminating a function.
