Variables in expressions default to a numeric context. For example, the
expression:
$cur_role
returns the numeric value of $cur_role, which is 0 when $cur_role := "ACTIVE".
Always force a string context by using quotes. Change your last two expressions
to this:
old_role, "$cur_role", CALCULATION, ""
cur_role, "$role", CALCULATION, ""
(The only exception to this rule is the =~ operator which promotes the left
argument to a string context automatically.)
