[SAC-HELP] Error messages from getfhv etc

[Neil Selby]

The sac_i/o functions getfhv, getihv etc print error messages to standard output if the related header variable is not defined, e.g.:

  ERROR 1336: Undefined header field value. DEPMIN

this seems an undesirable behaviour to me, since the functions already return an error value that the programmer can handle in their own way.

Is this the designed behaviour or is it something peculiar about my set-up that can be changed?


many thanks,

Neil
