I have recently installed NONMEM. I am using Digital Fortran on windows 98 platform. when I am trying to run NONMEM it is giving error as " out of environment space". Does any one experienced similar problem and what is the solution for this kind of error.

This is only a problem on Windows 98/95. I can't tell you exactly (since I'm running NT right now), but basically Right mouse button over the title bar of a dos window

Select "memory" find the drop down box for "Initial environment" and change it from "auto" to 1024. Click "Apply" I think it asks you if you want to use this for this instance or all instances, select all instances.

Good luck.

You need to change the properties of the MS-DOS Prompt shortcut you use to open the NONMEM DOS window. Find the shortcut e.g. on your Desktop. Right click on it and then click on Properties. Click on the Memory tab and enter 4096 in the Initial Environment box. Click OK. You should now have enough Environment space.

You have to adapt your COMSPEC variable. If I'm not misktaken, you have to add to the CONFIG.SYS file the following command:
The important part is the E:1024. This increases the envirnoment space NONMEM, or better the fortran complier, is compaining about. The path of the has to be adapted according to the directory where your is stored. Hope it works, I can't test it right now because I'm running Windows 2000.

Even I have had and still having problems installing NONMEM with Compaq digital fortran compiler in a Windows 98 environment. However, in my case Gobomax is looking in to it.
