Is that what the data looks like, or are the lines actually really long?

Will the process name always be NEWOLUF2?

Here's what I have so far, assuming the long lines were wrapped accidentally. It's much, much, much easier to write when you know what you're supposed to be operating on
Code:
$ cat begintrans.c
#include <stdio.h>
#include <string.h>
int main(void)
{
char buf[16384];
int transcount=0, elapsetotal=0;
while(!feof(stdin))
{
int newoluf=0, elapsetime=-1;
char timestamp[64]={0};
buf[0]='\0'; // Blank out buffer
while(strcmp(buf, "BEGINTRANS\n") != 0) // look for BEGINTRANS
if(fgets(buf, 16384, stdin) == NULL)
break; // EOF
if(feof(stdin)) break;
while(strcmp(buf, "ENDTRANS\n") != 0) // Look for ENDTRANS
{
const char *tsstr;
if(fgets(buf, 16384, stdin) == NULL)
break;
if(strstr(buf, "NEWOLUF2") != NULL)
newoluf=1;
if(tsstr=strstr(buf, "Timestamp"))
sscanf(tsstr, "Timestamp <%[^>]>", timestamp);
if(strncmp(buf, "ElapseTime", 10) == 0)
sscanf(buf, "ElapseTime <%d>", &elapsetime);
}
if((elapsetime>=0) && (timestamp[0]))
{
transcount++;
elapsetotal += elapsetime;
printf("trans %d, elapsetime %d, timestamp %s\n",
transcount, elapsetime, timestamp);
}
}
printf("Average elapsetime is %d\n", elapsetotal / transcount);
return(0);
}
$ gcc begintrans.c -o begintrans
$ ./begintrans < data
trans 1, elapsetime 745, timestamp 14Sep1111-07-37
trans 2, elapsetime 765, timestamp 14Sep1111-07-37
trans 3, elapsetime 579, timestamp 14Sep1111-07-37
trans 4, elapsetime 356, timestamp 14Sep1111-07-38
trans 5, elapsetime 651, timestamp 14Sep1111-07-41
trans 6, elapsetime 292, timestamp 14Sep1111-07-42
trans 7, elapsetime 345, timestamp 14Sep1111-07-52
Average elapsetime is 533

Why would you need to use this in a script?
Why can't you just use print to print out what you want printed in the begining and print for what you want at the end.
So this:
nawk 'BEGIN {print "this is the first line"}
{print $1 $2 $3}
{print $5 $6}
END {print "this is the last line"}'

tai64n
tai64n(8) System Manager's Manual tai64n(8)NAME
tai64n - puts a precise timestamp on each line.
SYNOPSIS
tai64n
DESCRIPTION
tai64n reads lines from stdin. For each line, it writes
1 an @,
2. a precise timestamp,
3. a space, and
4. a copy of the input line
to stdout. The timestamp indicates the moment that tai64n read the first character of the line.
tai64n does not allocate any memory after it starts.
TIMESTAMPS
Timestamps used by tai64n are 12-byte TAI64N labels in external TAI64N format, printed as 24 lowercase hexadecimal characters. You can use
tai64nlocal(8) to convert the timestamps to a human-readable format.
For example, the timestamp 4000000037c219bf2ef02e94 refers to the nanosecond beginning exactly 935467455.787492500 seconds after the begin-
ning of 1970 TAI; 37c219bf hexadecimal is 935467455, and 2ef02e94 hexadecimal is 787492500.
The current implementation of tai64n relies on the UNIX gettimeofday library routine to return the current time as the number of TAI sec-
onds since 1970-01-01 00:00:10 TAI. Beware that most gettimeofday implementations are not Y2038-compliant. Furthermore, most clocks are not
set accurately.
EXIT CODES
tai64n exits 0 when it sees end of input. It exits 111 without an error message if it has trouble reading stdin or writing stdout.
