+Some global variables can be set to affect Interchange:
+
+=over 4
+
+=item MV_DOLLAR_ZERO
+
+This determines what Interchange does to Perl's $0 variable, which
+contains the operating system's name of the running process, for
+example in the ps(1) or top(1) commands. Valid settings are:
+
+=back
+
+ Setting Result
+ (not set) 'interchange'
+ 0 (do nothing)
+ 1 'interchange --> (CATROOT)'
+ string 'string'
+
+=over 4
+
+=item
+
+Note that this is set globally once only when the Interchange daemon
+is started, so it's pointless to change the variable after that.
