Fine Print about Temporary Directory

This gives some fine print details you almost certainly do not need to know about the Directory for Temporary files.

(a) For version 3.32 (July 2008) or later, the default name of the Temporary Directory ends with the name of the EXE. For example, if you are running RunDYN2.EXE, this default name is something like

C:\Documents and Settings\pearson\Local Settings\temp\gptemp\RunDyn2.

(b) The first time you run any version 1.7 or later of RunDynam, the program sets the Temporary Directory equal to a default value. This default value depends on the setting of the Environment variables GPTEMP, TMP and TEMP.

If Environment variable GPTEMP is set, the Temporary Directory is the RDYNTEMP subdirectory of the directory to which GPTEMP points. For example, if Environment variable GPTEMP is set equal to C:\XXX, the default temporary directory is C:\XXX\GPTEMP\RDYNTEMP.

The RDYN part of RDYNTEMP in these names may be different for the model-specific versions of this software -- for example, it is RMONTEMP for the MONASH model version of this software.

You can set the value of Environment variable GPTEMP. Doing this is the best way to resolve problems with the Temporary Directory since GPTEMP only affects GEMPACK windows programs (whereas the value of TMP -- see below -- may affect other programs).

(c) If Environment variable GPTEMP is not set, the Temporary Directory is set equal to the GPTEMP\RDYNTEMP subdirectory of the directory to which Environment variable TMP points. For example, if Environment variable TMP is equal to c:\TMP and Environment variable GPTEMP is not set, the the default temporary directory is c:\TMP\GPTEMP\RDYNTEMP.

The value of Environment variable TMP is always set as part of Windows installation. You can change the value of Environment variable TMP. However changes in the value of TMP may affect other programs whereas changes in the value of GPTEMP will only affect the GEMPACK Windows programs.

(d) In the unlikely event that Environment variable TMP is not set, RunDynam puts its temporary files into the GPTEMP\RDYNTEMP subfolder of the folder to which Environment variable TEMP points (if that is set) or of the Windows directory (if TEMP is not set).

(e) Once you have run any recent version of RunDynam (1.7 or later), the only way you can change the Temporary Directory is to use the menu item Specify Temporary Directory under the Options menu. Resetting the values of the Environment variables GPTEMP or TMP has no effect since RunDynam remembers the Temporary Directory from the last time you ran RunDynam. [In this respect, RunDynam is like the other Windows programs WinGEM, RunGEM and AnalyseGE but is different from ViewHAR, ViewSOL and TABmate which are always influenced by changes in TMP and/or GPTEMP.]
