FILE Path to the .a4c or .a4l file that you want to open |
24 |
(note: if the path is not an absolute path and can |

.SH DESCRIPTION |
29 |
|
30 |
\fBascend\fR will run the new PyGTK GUI for ASCEND. It gives console output |
31 |
as well as using a GTK window. |
32 |
|
33 |
\fBASCEND\fR (or \fBascend\fR) is modelling program that allows you |
34 |
to solve systems of equations. You write model files (*.a4c) that describe |
35 |
your system of equations, then you load them into the ASCEND GUI and examine |
36 |
and solve your equations. For more information see the ASCEND wiki at |
37 |

.SH ENVIRONMENT |
41 |
|
42 |
A number of environment variables are available for \fBascend\fR: |
43 |
|
44 |
ASCENDLIBRARY |
45 |
Path to ASCEND model files and external libraries. |
46 |
|
47 |
ASCENDSOLVERS |
48 |
Path to ASCEND solvers. When searching for solvers, this path |
49 |
variable is used first, then ASCENDLIBRARY is searched next as |
50 |
a fallack, and in order to allow users to use solvers stored in |
51 |
their user-configured model folder. |
52 |
|
53 |
CONOPT_PATH |
54 |
Path to libconsub3.so, if you have it. Usually defaults to /usr/lib if |
55 |
not defined. |
56 |
|
57 |
.SH USER SETTINGS |
58 |
|
59 |
ASCEND's PyGTK GUI uses a file ~/.ascend.ini to set and store user |
60 |
preferences. This file includes a setting for the value of ASCENDLIBRARY |
61 |
that is used if the variable is not present in the environment. |
62 |
|
63 |
Also kept in the .ascend.ini file are details about preferred units of |
64 |
measurement, and the most recent File..Open path, and the current |
65 |
Solver selection. More things will be stored in .ascend.ini over time. |
