Var_Parse: Separate different error states by introducing an else block after a return. Move assignments to {freePtr, dynamic, start} closer to the return statements to clarify which variables are actually used for communication between the losely coupled blocks of the code. Clear up an if-expression to make common structures of the conditions clearer. Use strchr instead of switch statements to check for a character beeing a member of a set.
