HL7Spy 2.1.268 Released

  • Improvement – New and improved Field/Component/Sub Component Statistics Feature.
    • Very fast navigation of messages with matching fields.
    • Ability to select multiple items in the Statistics Grid, and navigate to matching messages. For example, below selecting ‘O’ and ‘OP’ in the Statistics Grid and then clicking the Next/Previous Arrow buttons navigates to messages in the tab that have either a PV1-2 field equal to ‘O’ or ‘P’.
    • Ability to select multiple items in the Statistics Grid and have messages meeting the criteria placed into separate tabs. For example, clicking the “All” button in the case below would create 2 tabs: one with messages where PV1-2 = ‘O’ and the other where PV1-2 = ‘OP’. Holding the Control Key down and clicking the “All” button will place messages with either PV1-2=’O’, or PV1-2=’OP’ into a single tab. – Requested by Cleveland Clinic
