			float c, d;
			The definition of float variables ‘c’ and ‘d’ is illegal, because it occurs after
			executable code ‘b = a’
30		Variable is undefined	This error appears if iteration variable at ‘for’ statement is not defined before
			it.
			For example,
			function foo (int a) ** Function definition
			for k = 1 : 10 ** Start ‘for’ loop
			a = k ;
			end ** End ‘for’ loop
			return ; ** Function end
			The iteration variable ‘k’ is not defined before its use.
31		Bad separator between	Bad separator between dimensions (not comma). This error is unused,
		dimensions	because currently it is allowed only one-dimensional arrays and no needs in
			separator between dimensions.
32		Bad variable dimension	Legal variable dimension must be a positive number inside square brackets. If
			the expression inside square brackets is not evaluated into a number or this
			number is less then one (zero or negative), it’s illegal.
			For example,
			int arr[-12];
			Variable dimension is negative.
33		Bad function format	This error appears at the function definition in the following cases:
			1. Illegal function name – not distinct or empty, etc
			2. Function definition does not match to its prototype
			For example,
			function foo (int a) ; ** Function prototype
			function foo (float a) ** Function definition
			Type of input arguments at the function definition and its prototype does not
			match.
34		Illegal minus	Minus is illegal in the following cases:
			1. Minus before function call with multiple output arguments
			2. Minus before round parentheses with multiple expressions inside it.
			For example,
			[a,b] = -foo(c) ;
			-(2+3, c/5);
			The first example has illegal minus before function call with multiple
			outputs.
			The second example has illegal minus before multiple expressions within
			round parentheses.
35		Empty program	User program is empty
36		Program is too long	User program exceeds maximal admissible length
37		Bad function call	The following reasons cause this error:
			1. Attempt to jump at the ‘goto’ statement to the function with non zero
			number of input or output arguments
			2. Consider example:
			[a,b,c] = foo(x,y) + 5;
			This sentence is illegal.
			The Compiler checks if there is an expression terminator straight after
			function call with multiple outputs. Otherwise it sets this error.
38		Expression is expected	This error appears when expected expression is absent. It may occur at ‘wait’,
			‘until, ‘while’, ‘if’, ‘elseif’, ‘switch’ and ‘case’ statements.
			For example,
			if
			a = 0
			end
			An expected expression after ‘if’ is absent.
