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.
