CLI parameter is not being replaced in if statement in JBoss EAP 6?

Issue

• I execute a simple CLI script:

/host=${HOST-01}:read-attribute(name="name")
if (result == "${HOST-01}") of /host=${HOST-01}:read-attribute(name="name")
   /host=${HOST-01}:write-attribute(name="name", value="${HOST-01}-test")
else
  /host=${HOST-01}:write-attribute(name="name", value="${HOST-01}")
end-if
/host=${HOST-01}:read-attribute(name="name")

• It is not working for parameter "${HOST-01}" but working if I use hard coded value. What is the cause of this?
• The same script is working using bash variables and not when using a properties file to pass parameter values. why?
