The number of elements of a long string (char array) must always include the
terminating nil character, thus an empty string must have an element count of
one, not zero.  If you don't include the terminator in your element count your
string might get old garbage appended to it.

Ah, protocol...

So I must initialize NORD to 1 as well?

record(waveform, "$(P)AmpExpr-SP") {
 field(FTVL, "CHAR")
 field(NELM, "100")
 field(PINI, "YES")
 field(NORD, "1")
}
record(aSub, "$(P)AmpExpr-Calc_") {
 field(FTA , "CHAR")
 field(NOA , "100")
 ...
}
