Expressions calculate a result and substitute the result in place of the expression much like variable references.
|
||
|
|
* Are enclosed in ''' '' !-${=-! '' ''' and ''' '' !-=}-! '' ''' delimiters.
|
||
|
|
* May appear anywhere a variable is allowed.
|
||
|
|
* May contain the following operators:
|
||
|
|
* + - * / ^
|
||
|
|
* unary -
|
||
|
|
* cos sin tan
|
||
|
|
* ( )
|
||
|
|
* E notation, e.g., 12E+3

Given:

{{{!define X {1}
|
||
|
|
!define Y {2}
|
||
|
|
!define Z {3} }}}
|
||
|
|
|
||
|
|
The following expressions yields 10: {{{ !-${= ${X} + ${Y} + ${Z} + 4 =}-! }}}

|
|
!define Y {2}
|
||
|
|
!define Z {3}
|
