24		Name is keyword	Variable or function name is the same as some keyword. This error may
			appear if variable name is identical to some auto routine name.
			For example,
			int switch;
			‘switch’ is keyword, so its use as variable name is illegal.
25		Name is not distinct	This error occurs if some variable or function name is not distinct.
			For example,
			int foo ;
			function foo (int a)
			Function and variable have the same name ‘foo’,
			One more example,
			function foo (int a ) ** Function definition
			int a ; ** Local variable definition
			Definition of the local variable ‘a’ is illegal, because this function is already
			contains local variable ‘a’ as input argument.
26		Variable name is	This error occur in the following cases:
		invalid	1. Variable or function name starts from digit or underscore, but not
			from letter
			2. Variable or function name is empty
			3. At the variable definition line there is a comma as a separator
			between variables, but variable name after a comma is absent.
			For example,
			int _abc ;
			function (int a)
			int a, b,
			In the first example variable name has leading underscore.
			In the second example variable name is absent after a comma.
			In the third example function name is absent after the keyword ‘function’.
27		Bad separator between	The only legal separator between variables at the variable definition line is
		variables	comma. After variable name either variable separator (comma) or expression
			terminator is expected. Any other symbol causes to this error.
			For example,
			int a b;
			A command as variable separator is absent between ‘a’ and ‘b’.
28		Illegal global variable	Global variable must be declared inside function with the keyword ‘global’
		definition	and must be defined before this function. This error appears only if the
			keyword ‘global’ was used in the bad context:
			1. The keyword ’global’ was used outside function.
			2. Variable that is declared as global inside function is not defined
			before.
			3. Type of the variable at the definition outside the function differ from
			the type of the declaration inside function
			For example,
			int a1 ; ** Global variable definition
			function foo (int a) ** Function definition
			global float a1; ** Declaration of the global variable inside function
			Type of variable a1 at its definition is ‘int’, while inside function is declared
			as ‘float’.
29		Bad variable definition	All local variables must be defined at the beginning of the function. Any
			variable definition after some executable code in the function is illegal.
			For example,
			function foo (int a) ** Function definition
			int b ;
			global int a1;
			b = a ; ** Executable code
