macro hdrval and syntax error
2017-06-23 21:56:29
Hello everyone, I'm a new SAC user, and I'm doing some exercise about macros (following "The seismic analysis code, a primer and user's guide" book), but I'm finding several difficulties about some commands, like HDRVAL. It's like if this command is not installed. Another error is a syntax one, with the commands item, itemcount and existbb. Example of the macro:

setbb rts "ABC 123 XYZ"
message "Does str exist? (existbb str)"
Syntax error: message "Does str exist? (existbb str)"
^
My SAC version is 101.6a

Can someone help me with this?

Thanks,
Simona

    Hi Simona,
    My understanding is that some SAC functions used in the SAC primer are
    implemented in MacSAC and not in IRIS SAC. Perhaps HDRVAL is one of those
    functions. As per your little macro, this should work,

    SAC> setbb rts "ABS 123 CCC"
    SAC> message "Does str exist?(%rts%)"
    Does str exist?(ABS 123 CCC)
