+ *  $FUNCNAME$
+ *	MEMVARBLOCK
+ *  $CATEGORY$
+ *	variables management
+ *  $ONELINER$
+ *	Returns a codeblock that sets/gets a value of memvar variable
+ *  $SYNTAX$
+ *	MEMVARBLOCK( <cMemvarName> )
+ *  $ARGUMENTS$
+ *	<cMemvarName> - a string that contains the name of variable
+ *  $RETURNS$
+ *	a codeblock that sets/get the value of variable
+ *  $DESCRIPTION$
+ *	This function returns a codeblock that sets/gets the value of
+ *	PRIVATE or PUBLIC variable. When this codeblock is evaluated
+ *	without any parameters passed then it returns the current value
+ *	of given variable. If the second parameter is passed for
+ *	the codeblock evaluation then its value is used to set the new
+ *	value of given variable - the passed value is also returned
+ *	as a value of the codeblock evaluation.
+ *  $EXAMPLES$
+ *	PROCEDURE MAIN()
+ *	LOCAL cbSetGet
+ *	PUBLIC xPublic
+ *	
+ *	cbSetGet = MEMVARBLOCK( "xPublic" )
+ *	EVAL( cbSetGet, "new value" )
+ *	? "Value of xPublic variable", EVAL( cbSetGet )
