= <expr1> [, <expr2> ...]

-----------------------------------
Evaluate a list of expressions.
-----------------------------------

The = command evaluates one or more expressions <expr1>, <expr2> ... ,
<exprN> and discards any return value.  This is particularly useful when
a function has a desired effect but there is no need to assign the
function's returned value to a memory variable or field.

For example, to turn the insert mode on you can issue the command:

= INSMODE(.T.)

The INSMODE function normally returns a true (.T.) or false (.F.) value.
In this example the function is executed but the returned value is
suppressed.

Note that the equal sign = can also be used as an operator in logical
expressions to make a comparison.  It may also be used to assign values
to arrays and memory variables.  In these two cases the equal sign is
not used as a command.
