My regular IOC has a waveform record with the initial value ["aaa", "bbb", "ccc"] as follows,

caput CLI without double quotation marks will write data to different elements of the waveform record as follows,

caput CLI with double quotation marks around the whole data will write the data to the first element of the waveform record as follows,

In addition, if the data to be writen exceeds the count limit of the recrod or the casPV, caput CLI will return an error as follows instead of crashing the server side. 

Thanks,

Lin

A regular IOC with the following waveform record works properly with the caput CLI comes with EPICS 3.14.12.8 or EPICS 7.0.7.

record(waveform, "wfExample")

{

        field(DTYP, "Soft Channel")

        field(FTVL, "STRING")

        field(NELM, "3")

        field(INP, ["aaa", "bbb", "ccc"])

}

Hm...

Can you double check if that is a single element ("xxx yyy zzz") or three elements ("xxx", "yyy", "zzz") in the record? (Might look the same on the command line.)
