SetEnvironmentVariable()
"This function has no effect on the system environment variables or the environment variables of other processes."

But you can do it this way:
"Calling SetEnvironmentVariable has no effect on the system environment variables. To programmatically add or modify system environment variables, add them to the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\Environment registry key, then broadcast a WM_SETTINGCHANGE message with lParam set to the string "Environment". This allows applications, such as the shell, to pick up your updates. Note that the values of the environment variables listed in this key are limited to 1024 characters."

Vilian,

Try to use 0xFFFF instead of -1

Also use "Environment" instead of "TESTE3"

Vilian,

Finally, use 0 (zero) instead of "VFAPORTAL" when calling SendMessage()

Antonio,

I did not understand. The command would be thus then?

SendMessage(0xFFFF,WM_SETTINGCHANGE,0,"Environment")

But as I define that changeable it goes to be modified and which the new value?

Vilian,

> SendMessage(0xFFFF,WM_SETTINGCHANGE,0,"Environment")

Yes, that is what I meant

> But as I define that changeable it goes to be modified and which the new value?

You set the new value in the registry, then notify all the windows about such change.

It should work that way

Antonio,

grateful for the help.

But as sending this value for the registry?

Vilian,

Please review FWH\samples\testrg32.prg

Vilian,

Have you tried to close and restart the application after such change ?
