Thank you Matthieu, for your solution, I've just tried it.
Eric,
In my genSub, I will analyse the bits of a Defect word, and translate
each bit field in a string, then I output an array where the strings are
available for operator display.
Implementation with several mbbi records cannot fulfill all my needs, so
I do the analysis with genSub.
All this to explain I am not concatenating several mesages so your
proposal is not adequate, thanks anyway.
However, don't hesitate if you have any other suggestion of implementation.
Best Regards.

Are you trying to just send and print the concatenated error message
strings?
Perhaps something like this is adequate?
FTVN: CHAR
NOVN: 120
int nleft = precord->novn;
char *np = (char *)precord-:>valn;
int n;
n = epicsSnprintf(np, nleft, "Defect string 1. ");
nleft -= n;
np += n;
.
.
n = epicsSnprintf(np, nleft, "Defect string 2. ");
nleft -= n;
np += n;
.
.

Hi all,
I have configured a gensub record to output a string array but this
doesn't work.
I set the following genSub fields:
FTVN:STRING
NOVN:12
in my process function I do the following:
sprintf ((char*)precord->valn, "Defect String 1");
sprintf ( (char*)(((char**)(precord->valn))+1), "Defect String 2");
When I execute the IOC, the output is the following:
epics> dbgf IOCASTE-TST:ProcessDynamicModbusTable.VALN
DBR_STRING: DefeDefect String 2
the second string has overwritten the first one.
It seems that there only one string
thanks in advance for your help.
