AUTOEXEC.OMS - Automatically Executed Commands and Defined Constants
See Also: clear , include , path , pi , mlmode_autoexec

Description
The file autoexec.oms is automatically included when O-Matrix starts and after every clear command. The default copy of this file is in the installation directory (usually c:\omwin). It sets the search path to include the function, lib, toolbox, tools, and tecplot directories in that order. It also defines the following constants:
Name Meaning
DQUOTE " character
TAB tab character
NEW_LINE new line character
NEW_PAGE new page character
PI double-precision pi
REAL_EPSILON single precision machine epsilon
DOUBLE_EPSILON double-precision machine epsilon
REAL_MAX maximum normalized single-precision number
DOUBLE_MAX maximum normalized double-precision number
REAL_MIN minimum positive normalized single-precision number
DOUBLE_MIN minimum positive normalized double-precision number
INT_MAX maximum allowable integer constant
NAN double-precision version of not a number
INF double-precision version of infinity
OM_INSTALL directory where O-Matrix is installed
TECHOME directory where Tecplot is installed
Other Autoexec Files
You can also create another file called autoexec.oms and put it either in the current directory, or in a directory that comes before the installation directory in the search path . If you do this, O-Matrix will use your version of the autoexec.oms file.

The O-Matrix Mode Search Path
The following O-Matrix code sets the search path for O-Matrix mode:
#
local ominstall = [";", NEW_LINE, OM_INSTALL]
path([    ...
     OM_INSTALL,                ...             
     ominstall, "\function",    ...
     ominstall, "\lib",         ...
     ominstall, "\toolbox",     ...
     ominstall, "\tools",       ...
     ominstall, "\ipacks",      ...

     ominstall, "\stsa\rng",     ...

     ominstall, "\stsa\stats",  ...

] )
The Mlmode Search Path
If you own a Matlab license and wish to use the m-files from that distribution set the MathWorks variable to the location of those files and set the variable Octave = false.

local ominstall = [";", NEW_LINE, OM_INSTALL]
local MathWorks = [";", NEW_LINE, "c:\m4files"]
local Octave    = true 
#
if Octave then begin
     mlpath([                   ...
     mlpath,                    ...
     ominstall, "\toolbox",     ...
     ominstall, "\octave"       ...
     ] )
end else begin
     mlpath([                   ...
