I have a waveform record with FTVL set to String, but some of the
elements are actually floating point numbers and I would like to
separate them all out into individual records.

Has anyone ever tried using multiple subArray records with different
FTVL settings for this purpose?  I've tried to do this but can't get it
to work properly, here's my problem:

Using the following database, I can do 'caput -a ARRAY 1 2 3 4' - no
problem, P1=1, P2=2, P3=3 and P4=4.  If I do 'caput -a ARRAY 3 4 "any
string" 5' - P4 does not get updated, so I get P1=3, P2=4, P3="any
string", P4=4.  In fact it seems that any numbers appearing after the
string element in the array do not get updated.

Any ideas? Would you expect this to work?

record(waveform, "ARRAY") {
  field(NELM, "4")
  field(FTVL, "STRING")
}

record(subArray, "P1") {
  field(FTVL, "FLOAT")
  field(INP, "ARRAY CP")
  field(NELM, "1")
  field(MALM, "4")
  field(INDX, "0")
}

record(subArray, "P2") {
  field(FTVL, "FLOAT")
  field(INP, "ARRAY CP")
  field(NELM, "1")
  field(MALM, "4")
  field(INDX, "1")
}

record(subArray, "P3") {
  field(FTVL, "STRING")
  field(INP, "ARRAY CP")
  field(NELM, "1")
  field(MALM, "4")
  field(INDX, "2")
}

record(subArray, "P4") {
  field(FTVL, "FLOAT")
  field(INP, "ARRAY CP")
  field(NELM, "1")
  field(MALM, "4")
  field(INDX, "3")
}

Thanks,

Emma
