Nice angle Aia. That should work provided that none of the fields are broken after a digit as the last character and that the last character in the last field is a digit..

Given what was stated in post #3, you might also try something like:
Code:
awk '
BEGIN {	FS = OFS = "|"
}
NR == 1 {
	num = $1
	printf("%s", $0)
	next
}
{	printf("%s%s", $1 == num ? "\n" : " ", $0)
}
END {	print ""
}' file.txt

which captures the 1st field from the 1st line in the input and joins following lines with a <space> separator until it find another line with the same first field.

As always, if you want to try this on a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk or nawk.
