Table 2-2 shows the types of values you can use within the context of

Table 2-2: Target Language Values
Value Type
String
Example Description
"Boolean" 1==1
Result of a comparison or
other Boolean operator.
Note: There are no Boolean
constants, and Boolean
values are 1 or 0 as in C. 1 is
still a number and not a
Boolean value.
"File" %openfile x
String buffer opened with
%openfile.
"File" %openfile x = "out.c"
File opened with %openfile.
"Function" %function foo…
A user-defined function.
"Identifier" abc
Identifier values can only
appear within the
.rtw file
and cannot appear in
expressions (within the
context of an expression,
identifiers are interpreted
as values). To compare
against an identifier value,
use a string; the identifier
will be converted as
appropriate to a string.
"Macro" %define MACRO …
A user-defined macro.
