92 Plus Sierra C Assembler Reference Manual
Not for Distribution
Beta Version February 2, 2001
The following Sierra C utilities support command line wildcard expansion:
nm68
Symbol Table Name Utility
size68
Object File Size Utility
1.3. Environment Variables
Some Sierra C utilities need to know the location of certain standard directories
to locate various files. For example, the compiler must know where to search for
files specified by the
#include
filename
preprocessor directive. Since this
information varies depending on the installation, the utilities examine
environment variables to obtain information on the locations of these standard
directories.
Figure 1.1 shows the default standard include (
include
), standard library (
lib
),
executable (
bin
), and temporary (
tmp
) directories that are created by appending
subdirectory names to the directory specified by the
SIERRA
environment
variable. The
SIERRA
environment variable will be set when the setup program
for the TI
FLASH
Studio is executed. The
SIERRA
environment variable must be
set before using any of the Sierra utilities.

1: Environment Variables
Depending on which environment variables are set, the utilities that generate
temporary files will put their files in one of four places. The three environment
variables
TMP68
,
TMP
, and
SIERRA
are searched for in the order listed with the
search terminating after the first defined variable is located. If either
TMP68
or
TMP
is defined, the directory specified by that environment variable is used to
hold temporary files. If the
SIERRA
environment variable is the only variable
