There are at least two ways of getting desired value using 4test script. One of them using SYS_Execute function and one more is with SYS_GetEnv function. The both 4test code examples are posted below:

The SYS_Execute function uses Windows XP command prompt networking tool hostname which displays the host name portion of the full computer name. The SYS_GetEnv function returns the value of the COMPUTERNAME environment variable. The second method would work a little bit faster and definitely would be preferable for extensive regression testing.
