script
create page	SuitePage	with content	!define TEST_SYSTEM (slim) !define VARIABLE (some value) !path lib/*.jar
make	SuitePage	a suite page
create page	SuitePage.ScenarioLibrary	with content	Scenario Library: "${VARIABLE}"
create page	SuitePage.TestPage	with content	Test Page: "${VARIABLE}"
make	SuitePage.TestPage	a test page

You would expect the variable to be substituted when the test page is executed:

script
check	request page	SuitePage.TestPage?test	200
show	content
ensure	content contains	Scenario Library: "some value"
ensure	content contains	Test Page: "some value"

Now, it we execute from Suite level, the variable should be substituted too:

script
check	request page	SuitePage?suite	200
show	content
ensure	content contains	Scenario Library: "some value"
ensure	content contains	Test Page: "some value"
