Sorting problems

Sorting problems

(OP)
I have a sorting question. Picture a datafile with about ten fields seperated by ‘:’.
The first field is unique and nummeric. As records are printed on the bottom of the datafile after a modification I would like to do a  sort on the first field of the datafile to move the modified record to the right spot.

With the help of some manuals I tried something like this:

#sort prop
open (data, "<$profile") or &error("Unable to open the data file");
@data=<data>;
close(data);
@datax=split(/:/, $data);
@data = sort {$a <=> $b} @datax;
open (wdata, ">$profile") or &error("Unable to write to the data file");
print wdata @data;
close(wdata);

Obviously this is not correct as the whole database is deleted after this!

Hopefully there is somebody who can tell me what I'm doing wrong?

RE: Sorting problems

Think it is solved.

#sort prop
open (data, "<$profile") or &error("Unable to open the data file");
@data=<data>;
close(data);
@data = sort {$a <=> $b} @data;
open (wdata, ">$profile") or &error("Unable to write to the data file");
print wdata @data;
close(wdata);

Jett,
