each string's offset by MAX_STRING_SIZE, try the following

for (i=o;i<precord->novn,i++)
snprintf ((char*)precord->valn+i*MAX_STRING_SIZE,MAX_STRING_SIZE, "Defect String %d",i );

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.
