Working with the Target Language

2-24

Extending the former example to a loop that rolls:

%language "C"

%assign ablock = BLOCK { Name "Hi" }

%roll Idx = [ 1:20, 21, 22, 23:25, 26:46], lcv = 10, ablock

Block[%< lcv == "" ? Idx : lcv>] *= 3.0;

%endroll

This TLC code produces the output:

{

int i;

for (i = 1; i < 21; i++)

{

Block[i] *= 3.0;

}

Block[21] *= 3.0;

Block[22] *= 3.0;

Block[23] *= 3.0;

Block[24] *= 3.0;

Block[25] *= 3.0;

for (i = 26; i < 47; i++)

{

Block[i] *= 3.0;

}

Object-Oriented Facility for Generating Target Code

The Target Language Compiler provides a simple object-oriented facility. The

language directives are:

%language string

%generatefile

%implements

This facility was designed specifically for customizing the code for Simulink

blocks, but can be used for other purposes as well.

The

%language directive specifies the target language being generated. It is

required as a consistency check to ensure that the correct implementation files

are found for the language being generated. The

%language directive must
