Yeah perfect... As u said the sorting is to be by default otherwise results would be ambiguous..

But did you notice something.. unlike other languages, in awk there is no necessity to declare a variable. example is this field1 and field2... and no initialization also is required....


Too good a program.. in my program that i posted i need to change the max variable everytime when the width of the record is changed... and so is the offset for the firstcol, secondcol and the thirdcol...

So I think the one that u sent would be the efficient one..
Thanks a lot for your time and explanation...

Thanks,
Nisha

PMNAMEINDOM(3)						     Library Functions Manual						    PMNAMEINDOM(3)

NAME
pmNameInDom - translate an instance identifier into an instance name C SYNOPSIS
#include <pcp/pmapi.h> int pmNameInDom(pmInDom indom, int inst, char **name); cc ... -lpcp DESCRIPTION
For the instance domain indom, in the current Performance Metrics Application Programming Interface (PMAPI) context, locate the instance with the internal instance identifier given by inst, and return the full external instance identification via name. The value for the instance domain indom is typically extracted from a pmDesc structure, following a call to pmLookupDesc(3) for a particu- lar performance metric. The space for the value of name will have been allocated in pmNameInDom with malloc(3C), and it is the responsibility of the caller to free(3C) the space when it is no longer required. pmNameInDom returns zero on success. SEE ALSO
PMAPI(3), pmGetConfig(3), pmGetInDom(3), pmLookupInDom(3), pmNameInDomArchive(3), pcp.conf(5) and pcp.env(5). DIAGNOSTICS
PM_ERR_INDOM indom is not a valid instance domain identifier PM_ERR_INST The instance identifier inst is not known for the instance domain indom in the current PMAPI context Performance Co-Pilot PCP PMNAMEINDOM(3)
