    PI Performance Equations: How to dynamically set NEXTVAL function TIME argument...

    kdoyle01

      Context: Using PI Performance Equations NEXTVAL function as data source for Processbook display VALUE controls.

       

      I need to set the TIME argument value dynamically, instead of using a static value.  That is, rather than using this format:

      NextVal('Sinusoid','T+23h+40m')

       

      I need to dynamically set the HOUR value, similar to:

      NextVal('Sinusoid','T' + '+' + Hour('*') + 'h+40m')

       

      However (if it's even possible), I can't figure out the correct syntax; keep getting PE Equation parsing errors.

       

      I've tried using the CONCAT and TEXT functions, to construct the TIME value, to no avail.  (On a related note: why is a period (.) appended to the strings returned by those functions???)

       

      Thanks,
