Dear Mei,
revise your first line as follows,

setbb log '&1,kstnm& .split'

As per the second line with an evaluation, there may be a issue. I tried to
recreate the following example given on p.49 in SAC Primer and came across
a similar problem. Perhaps SAC developers can provide an explanation.

SAC Primer Example
----------------------------

SAC> setbb x 1 ;* set x to 1
SAC> message "sqrt (%x% + %x%) is (sqrt (%x% + %x%))"
sqrt 2.000000 is 1.41421


My result on SAC 101.6
--------------------------------
SAC> setbb x 1
SAC> message "sqrt (%x% + %x%) is (sqrt (%x% + %x%))"
sqrt (1 + 1) is (sqrt (1 + 1))

Thanks !

Januka.

Hi,

this is a border effects, the sac command taper is sufficient to avoid it.

Hello,
I run band pass filter using command as:
bp co 0.01 0.1 n 4 p 2
the original waveform is the top one (with dt=1.0s, npts=7200),
the filtered one is at the bottom, why there is a strange wiggle in the
left edge?<a.jpg>

I tried your way and it didn't produce the expected results. Though SAC
recognizes the sign of parenthesis now, it doesn't calculate or perform the

    Dear Januka,

    Thank you very much for your help and reproducing a similar problem with
    SAC 101.6a.

    The first line works now in your way "setbb log '&1,kstnm& .split'".

    And for the second line with an evaluation, it seems be a problem with SAC
    101.6a.

    Hope SAC developers can provide a solution.

    Best wishes,

    Mei

    Dear Mei,
    revise your first line as follows,

    setbb log '&1,kstnm& .split'

    As per the second line with an evaluation, there may be a issue. I tried
    to recreate the following example given on p.49 in SAC Primer and came
    across a similar problem. Perhaps SAC developers can provide an explanation.

    SAC Primer Example
    ----------------------------

    SAC> setbb x 1 ;* set x to 1
    SAC> message "sqrt (%x% + %x%) is (sqrt (%x% + %x%))"
    sqrt 2.000000 is 1.41421


    My result on SAC 101.6
    --------------------------------
    SAC> setbb x 1
    SAC> message "sqrt (%x% + %x%) is (sqrt (%x% + %x%))"
    sqrt (1 + 1) is (sqrt (1 + 1))

    Thanks !

    Januka.

    Dear Milton,

    Thank you very much for your time!

    I tried your way and it didn't produce the expected results. Though SAC
    recognizes the sign of parenthesis now, it doesn't calculate or perform
    the
    function I want it does, such as add two numbers or concatennate two
    strings. While older version of SAC can do these jobs.

      Dear Januka,

      Is this ok to use without the quotes ?

      SAC> setbb xc 1.2
      SAC> setbb yc 3.4
      SAC> sc echo l %xc% ( %yc% + 0.01)
      l 1.2 3.41
      SAC> sc echo l %xc% ( %yc% + 0.01) >> tmp
      SAC> cat tmp
      l 1.2 3.41
      SAC>

      The quotes are used to identify strings, and no math within ( ) is executed within

      SAC> setbb x 1
      SAC> message "sqrt (%x% + %x%) is "(sqrt(%x% + %x%))
      sqrt (1 + 1) is
      1.41421
      SAC> message "sqrt (%x% + %x%) is (sqrt(%x% + %x%))"
      sqrt (1 + 1) is (sqrt(1 + 1))
      SAC>

      If anything, the Help pages should be changed to match the behavior, or we need to revert these changes.

      After I installed the latest version of SAC (101.6 for X86-64) I found that a piece of my SAC macro codes didn't work and which worked and still works well in the older version of SAC (101.3b for X86-64). The piece of codes and their corresponding output the two versions of SAC are as the following:

      101.3b version:

      setbb log " ( concatennate &1,kstnm& .split ) "
      message "%log%"
      HY16.split

      101.6a version:
      setbb log " ( concatennate &1,kstnm& .split ) "
      message "%log%"
      ( concatennate HY16 .split )

      Similarly,

      101.3b version:
      sc echo "l %xc% ( %yc% + 0.01)" >> split.pcf
      OUTPUT the following line into split.pcf:
      l 0.53125 0.6611112

      Whereas for 101.6a version:
      sc echo "l %xc% ( %yc% + 0.01)" >> split.pcf
      OUTPUT the following error message:
      sh: -c: line 0: syntax error near unexpected token `('

        Hi Brian,
        Yes! Evaluations work with the syntax you just suggested.

        If anything, the Help pages should be changed to match the behavior, or we

        Dear Januka,

        Thank you very much for your help and reproducing a similar problem with
        SAC 101.6a.

        The first line works now in your way "setbb log '&1,kstnm& .split'".

        And for the second line with an evaluation, it seems be a problem with SAC
        101.6a.

        Hope SAC developers can provide a solution.

        Best wishes,

        Mei

        Dear Mei,
        revise your first line as follows,

        setbb log '&1,kstnm& .split'

        As per the second line with an evaluation, there may be a issue. I tried
        to recreate the following example given on p.49 in SAC Primer and came
        across a similar problem. Perhaps SAC developers can provide an explanation.

        SAC Primer Example
        ----------------------------

        SAC> setbb x 1 ;* set x to 1
        SAC> message "sqrt (%x% + %x%) is (sqrt (%x% + %x%))"
        sqrt 2.000000 is 1.41421


        My result on SAC 101.6
        --------------------------------
        SAC> setbb x 1
        SAC> message "sqrt (%x% + %x%) is (sqrt (%x% + %x%))"
        sqrt (1 + 1) is (sqrt (1 + 1))

        Thanks !

        HY16.split

        OUTPUT the following line into split.pcf:
        l 0.53125 0.6611112

        Whereas for 101.6a version:
        sc echo "l %xc% ( %yc% + 0.01)" >> split.pcf

          Thanks Brian and Januka help me out! The evaluations work now on SAC 101.6a
          without the quotes!

          Hi Brian,
          Yes! Evaluations work with the syntax you just suggested.

          Many thanks !

          The quotes are used to identify strings, and no math within ( ) is

          If anything, the Help pages should be changed to match the behavior, or
          we need to revert these changes.

          Dear Januka,

          Thank you very much for your help and reproducing a similar problem with
          SAC 101.6a.

          The first line works now in your way "setbb log '&1,kstnm& .split'".

          And for the second line with an evaluation, it seems be a problem with
          SAC 101.6a.

          Hope SAC developers can provide a solution.

          Best wishes,

          Mei

          Dear Mei,
          revise your first line as follows,

          setbb log '&1,kstnm& .split'

          As per the second line with an evaluation, there may be a issue. I tried
          to recreate the following example given on p.49 in SAC Primer and came
          across a similar problem. Perhaps SAC developers can provide an explanation.

          SAC Primer Example
          ----------------------------

          SAC> setbb x 1 ;* set x to 1
          SAC> message "sqrt (%x% + %x%) is (sqrt (%x% + %x%))"
          sqrt 2.000000 is 1.41421


          My result on SAC 101.6
          --------------------------------
          SAC> setbb x 1
          SAC> message "sqrt (%x% + %x%) is (sqrt (%x% + %x%))"
          sqrt (1 + 1) is (sqrt (1 + 1))

          Thanks !

          Januka.

          this is a border effects, the sac command taper is sufficient to avoid

          Dear Milton,

          Thank you very much for your time!

          I tried your way and it didn't produce the expected results. Though SAC
          recognizes the sign of parenthesis now, it doesn't calculate or perform
          the
          function I want it does, such as add two numbers or concatennate two
          strings. While older version of SAC can do these jobs.
