The DEFINE_VAR command allows you to define a variable and an associated value. You can then use the
defined variable name later wrapped in percent signs to have the defined value replaced in the script. This is
useful for things like defining a path or something at the top of a script that you can easily change in just one
place later.
The following parameters are required by the DEFINE_VAR command.
• NAME - specifies the variable name
• VALUE - specifies the variable value
Here is an example of a DEFINE_VAR command used to define a directory path for later use and then its
subsequent use:
DEFINE_VAR NAME="DATA_DIR" VALUE="c:\temp\export test"
IMPORT FILENAME="%DATA_DIR%\blue_springs.opt"
DIR_LOOP_END
The DIR_LOOP_END command ends a loop of commands over all of the folders within a directory. See the
DIR_LOOP_START command for details.
DIR_LOOP_START
Global Mapper User's Manual
The DIR_LOOP_START command begins a loop of commands over all of the folders within a directory (and
optionally its subdirectories) that match one or more filename masks. This is a powerful feature allowing you
to do things like easily batch convert a collection of files or perform any other supported operation over a
collection of files. You end a loop over the files in a folder using the DIR_LOOP_END command. Note that it
is also possible to nest loops.
For any commands found within a DIR_LOOP_START...DIR_LOOP end pair defining a loop, the following
special character sequences can be used anywhere (examples of what the values will be based on a current
filename of 'C:\data\my_file.dem' are listed):
• %DIR% - full path to current file (value is 'C:\data\')
• %FNAME_W_DIR% - full path and filename of current file (value is 'C:\data\my_file.dem')
• %FNAME% - filename of current file (value is 'my_file.dem')
• %FNAME_WO_EXT% - filename of current file without extension (value is 'my_file')
• %PARENT_DIR% - name of parent directory of file (value is 'data')
For a sample of the DIR_LOOP_START command in use, see the example at the bottom of this reference.
The following parameters are used by the DIR_LOOP_START command.
• DIRECTORY - specifies the directory to search for files in. If you leave this blank, the operation will
be based in the current folder.
• FILENAME_MASKS - space-separated list of filename masks to import. If no value is provided then
all files will be used.
