Basic expressions
The simplest expression is a single literal data value; for example,
6 // The number 6
"eloign" // The string "eloign"
You can use operators to join multiple literals; for example,
6 + 456 * 3 // The number 1374
"sep" + "a" + "rat" + "e" // The string "separate"
To see the value of an expression in the Command window, precede the expression with the ? symbol:
? 6 + 456 * 3 // Displays 1374
