Function

AUTO ( any nof(string) )

Syntax

AUTO( <expression>, <var1>, <var2>,... )

Description

'AUTO' associates the expression 'expression' with the variables 'var1', 'var2' etc. Whenever one those variables is evaluated, i.e., when its value is required, <expression> is automatically evaluated. This must assign a new value to the variable, otherwise an error is raised. The new value is then returned.

'AUTO' is a procedure, i.e., does not return a value.

Examples

AUTO(Bind("x_a",23),x_a); x_a;
AUTO( ReadLib("x_integer"), x_Int, x_Abs, x_Sign, x_Maximum, x_Minimum );
