by svorkoetter&#x40;maplesoft&#46;com on 4 Jun 2010 14:46 UTC**\nIn MSL 3.1, the block Modelica.Blocks.Continuous.TransferFunction contains this parameter declaration:\n```text/x-modelica\nparameter Real a[:] \"Denominator coefficients of transfer function\"\n  annotation(Dialog(group=\"y = (2*s+3)/(4*s2+5*s+6)*u is defined as b={2,3}, a={4,5,6}\"));\n```\n\nNotice that the parameter has no value _and_ no start value. In MSL 2.2.1, it did have a value of `{1,1}`.\n\nAlso, is that long ugly string really supposed to be displayed as the dialog box's group heading for this parameter??? Shouldn't that go into the string comment for the parameter instead? A better declaration for \"a\" (and likewise for \"b\") might be:\n\n```text/x-modelica\nparameter Real a[:] \"Denominator coefficients of transfer function (e.g., 4*s2+5*s+6 is specified as {4,5,6}).\"\n  annotation(Dialog(group=\"Numerator and denominator coefficients\"));\n```\n\n----\n\nMigrated-From: https://trac.modelica.org/Modelica/ticket/374"},"comment":{"url":"https://api.github.com/repos/tbeu/Modelica/issues/comments/268541851","html_url":"https://github.com/tbeu/Modelica/issues/374#issuecomment-268541851","issue_url":"https://api.github.com/repos/tbeu/Modelica/issues/374","id":268541851,"user":{"login":"modelica-trac-importer","id":22202507,"avatar_url":"https://avatars.githubusercontent.com/u/22202507?v=3","gravatar_id":"","url":"https://api.github.com/users/modelica-trac-importer","html_url":"https://github.com/modelica-trac-importer","followers_url":"https://api.github.com/users/modelica-trac-importer/followers","following_url":"https://api.github.com/users/modelica-trac-importer/following{/other_user}","gists_url":"https://api.github.com/users/modelica-trac-importer/gists{/gist_id}","starred_url":"https://api.github.com/users/modelica-trac-importer/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/modelica-trac-importer/subscriptions","organizations_url":"https://api.github.com/users/modelica-trac-importer/orgs","repos_url":"https://api.github.com/users/modelica-trac-importer/repos","events_url":"https://api.github.com/users/modelica-trac-importer/events{/privacy}","received_events_url":"https://api.github.com/users/modelica-trac-importer/received_events","type":"User","site_admin":false},"created_at":"2016-12-21T14:54:21Z","updated_at":"2016-12-21T14:54:21Z","body":"**Modified by dietmarw on 4 Jun 2010 14:46 UTC**"}}
