Missing '$' ?
subRecord.c:
static long process(subRecord *prec)
{
    long status = 0;
    int pact = prec->pact;
    if (!pact) {
        prec->pact = TRUE;
        status = fetch_values(prec);
        prec->pact = FALSE;
    }
    if (status == 0) status = do_sub(prec);
   ...
Hence, if INPA is not fetched successfully then the
subroutine is not executed as part of record processing.

I have a waveform and an aSub records. I want to transfer data from the waveform to the aSub record and I am having difficulties with that.
Here is my (simplified) waveform record:
record( waveform, "$(P):WF:REQUEST"){
   field( DESC, "struct for request")
   field( FTVL, "CHAR")
   field( NELM, "132")
   field( FLNK, "$(P):AS:REQUEST")
}
and here is my aSub record:
record( aSub, "$(P):AS:REQUEST"){
   field( DESC, "struct for request")
   field( INAM, "asInitialize")
   field( SNAM, "asRequest")
#  field( INPA, "(P):WF:REQUEST")
   field( FTA,  "CHAR")
   field( NOA,  "132")
   field( FTVA, "UCHAR")
   field( NOVA, "132")
}
When I process the waveform record, the asRequest routine gets called when the INPA field is commented out. However, when I uncomment the INPA field, asRequest routine no longer gets called when the waveform record is processed. Looking at the TIME field in the aSub record I can tell that the records is getting processed each time I process the waveform record, regardless if the INPA field is commented out or not.
Is it not allowed to transfer array of bytes from one record to another?
Is there a way to make that kind of data transfer?
Thanks in advance,
Zen
