namespace import ::cisco::eem::*
namespace import ::cisco::lib::*
if {[catch {array set testvar [context_retrieve TESTCTX testvar]} errmsg]} {
action_syslog msg "context_retrieve failed: $errmsg"
} else {
action_syslog msg "context_retrieve succeeded"
}
if {[info exists testvar]} {
action_syslog msg "testvar exists and is [array get testvar]"
} else {
action_syslog msg "testvar does not exist"
}

array set testvar "testvar1 ok testvar2 not_ok"
if {[catch {context_save TESTCTX testvar} errmsg]} {
action_syslog msg "context_save failed: $errmsg"
