Thahks, Huisheng Xu for your replay!!!
I have told about locale variable.
So, script on groovy
<script name="invoke script" var="text" lang="groovy" g="113,18,104,52">
<text>
int xxx = 13 + 54*12
println "$xxx -HELLO!"
</text>
<transition to="wait" />
</script>
Print following result 661 -HELLO!
And how we see int xxx = 13 + 54*12 remembered and printed !!!!!!!
But script on python language
<text>
yyy = 13 + 54*12
print yyy, "-HELLO!"
</text>
throw org.jbpm.api.JbpmException: script evaluation error: javax.script.ScriptException: groovy.lang.MissingPropertyException: No such property: yyy for class: Script1
It is strange!
Thanrs a lot Andrey.
