Hello Monks,
I have a file which looks like the sample data below

199901010000 0.316 6.1 263
199901010000 0.330 4.9 259


I have another file which looks like the sample data below

1999/01/01 00:00
1999/01/01 00:00

I would like to replace the first column (the bold section) of first data file with the contents of the second data file.

How would someone not well versed in programing do that with PERL?
thank you very much for any help.
