you want to declare a variable, then you must adhere to some rules.
Variable names can only be 6 characters long and must begin with an alphabetical character.
In choosing variable names you can include numbers after the first alphabetical character, but don't begin a variable name with a number.
Keep in mind that Fortran will not distinguish between upper and lower case variables, so if in your code you define `REAL Tc,TC', then the compiler will complain that you have tried to declare the same variable twice! Standard Fortran will exclusively be in uppercase since in the past punchcards only allowed for the upper case.
The exact size that a real variable can depend on the specifics of the computer.
