+If environment variables are expanded in the command parameters (see command descriptions), then you can write the variable along with the rest of the text inside the quotation marks. In other cases, you need to use concatenation of the variable with the text:
+<code>
+# environment variables are expanding in the command's parameter
+FileExist("%COMMANDER_PATH%\NoClose.exe")
+# environment variables are not expanding in the command's parameter
+StrLen(%COMMANDER_PATH% & "\NoClose.exe")
+</code>
