Hi,

I found a problem when I tried to call RTR_SLP variable:

rtrend
evaluate to X %RTR_SLP

and here is the SAC error:
Could not find variable RTR

    Dear Reza -

    This may be a bug, but an interim workaround involves avoiding the use of EVALUATE. Try SETBB:

    SETBB X %RTR_SLP%

    and then you can use %X% in calculations/expressions later (like you evidently intended by using EVALUATE).

      Dear George,

      Same error by %RTR_SLP%. I could not figure out why SAC cannot find VARS
      variable like RTR_SLP.

      Could you please look over that and run it on your machine.

        Hi Reza,
        As George pointed out, this could indeed be a bug. Try
        rtrend verbose on

        This is suppose to return variables associated with rtrend. When I run
        this, the system hangs. I remember in older versions of SAC, rtrend
        returned these variables automatically. I tested this with IRIS SAC 101.6
        on openSUSE 13.1 (Bottle).

        Januka.

        Dear Reza -

        Could be a SAC bug. Try this:

        SAC> fg seismogram
        SAC> rtrend
        Slope and standard deviation are: 0.23040E-03 0.35112E-02
        Intercept and standard deviation are: -0.10188 0.51758E-01
        Data standard deviation is: 0.32054
        Data correlation coefficient is: 0.20771E-02
        SAC> getbb
        NUMERROR = 0
        TABLES = ak135
        RTR_SLP = 0.23040E-03
        RTR_SDSLP = 0.35112E-02
        RTR_YINT = -0.10188
        RTR_SDDTA = 0.32054
        RTR_CORRCF = 0.20771E-02
        SACERROR = FALSE
        RTR_SDYINT = 0.51758E-01
        SAC> message "%RTR_SLP%"
        0.23040E-03
        SAC>

        You should see the BB variables set by rtrend and be able to retrieve their values. If not, it is a bug in blackboard variable handling in the version of SAC you are using.

          Same error again. Of course, I can see BB variables but message "%RTR_SLP%"
          cannot retrieve variable. May be a little bug brings about this, as you
          said.

          Thank you so much.
