in reply to Chess Board Single Loop

Like this

print for map{ join '|', map sprintf( "%02d", $_ ), $_*8+1 .. $_*8+8 } + 0 .. 7;; 01|02|03|04|05|06|07|08 09|10|11|12|13|14|15|16 17|18|19|20|21|22|23|24 25|26|27|28|29|30|31|32 33|34|35|36|37|38|39|40 41|42|43|44|45|46|47|48 49|50|51|52|53|54|55|56 57|58|59|60|61|62|63|64

Or perhaps this comes closer to your "one loop" ideal?:

print for unpack '(A24)*', join'|','01' .. '64', '';; 01|02|03|04|05|06|07|08| 09|10|11|12|13|14|15|16| 17|18|19|20|21|22|23|24| 25|26|27|28|29|30|31|32| 33|34|35|36|37|38|39|40| 41|42|43|44|45|46|47|48| 49|50|51|52|53|54|55|56| 57|58|59|60|61|62|63|64|

[erix]: if you're interested in tsv file reading in pg, look at file_fdw
[erix]: aka: create extension if not exists file_fdw;
[erix]: the annoying thing is that during setup of the 'foreign table' you have to specify all the columns. But that is reasonably automatable (just reading header line, and contruct the needed CREATE FOREIGN TABLE' statement)
