Function to perform macro substitution
&<memvar> | (<exp>)
The & macro function substitutes the contents of the specified <memvar> into the command line. To use a macro in the middle of a word, it is necessary to end the variable name with a '.'. Any type of memory variable can be substituted as a macro. The & macro function can also substitute the result of an expression into the command line. The <exp> must be enclosed in round brackets.
