Table 2-3: Target Language Expressions

Expression Definition

constant

Any constant parameter value, including

vectors and matrices.

variable-name Any valid in-scope variable name, including

the local function scope, if any, and the global

scope.

::variable-name Used within a function to indicate that the

function scope is ignored when looking up the

variable. See “Identifier Definition” on page

2-37.

expr[expr] Index into an array parameter. Array indices

range from

0 to N–1. This syntax is used to

index into vectors, matrices, and repeated

scope variables.

expr([expr[,expr]…]) Function call or macro expansion. The

expression outside of the parentheses is the

function/macro name; the expressions inside

are the arguments to the function or macro.

Note: Since macros are text-based, they

cannot be used within the same expression as

other operators.

expr. expr The first expression must be a valid scope;

the second expression is a parameter name

within that scope.

(

expr) Use () to override the precedence of

operations.

expr Logical negation (always generates 1 or 0 as

in C). The argument must be numeric or

Boolean.
