callScript() returns a value

[dilyanpalauzov]

… because the loaded script is in Xbase, in Xbase everything is an expression, there are no statements. Or may be it is not Xbase, but Xtend - https://eclipse.dev/Xtext/xtend/documentation/203_xtend_expressions.html ?

In any case, here a test: in openhab/scripts/a.script I put

logError('A', "STARTED")
7

and in rules/z.rules

rule "change"
when Item r3 changed
then
  logError("B", "when Item r3 changed")
  logError("D", "M " + callScript("a"))
end

Then I get in openhab.log:

2025-10-15 19:30:56.904 [ERROR] [org.openhab.core.model.script.A   ] - when Item r3 changed
2025-10-15 19:30:56.932 [ERROR] [org.openhab.core.model.script.B   ] - STARTED
2025-10-15 19:30:56.935 [ERROR] [org.openhab.core.model.script.D   ] - M 7

so the value 7 (last line/exrpession of the script) was received by the rule.
