..its stilll not running Im afraid..

$ awk 'BEGIN{FS=OFS=","}{for(i=1;i<=NF;i++){if($i=="0"){$i=""}}}1' SLsTester_DataFile.csv > SLsOUtputFile.csv;
awk: syntax error near line 1
awk: bailing out near line 1
/applmgr@fintest:~/finliveappl/su/11.5.0/payroll/gl $

..I've also tried running it within a script but it errors the same...

Thing is, as I have several date fields in each line ($5 $8 $9 $19 $20 $27) that may or may not need changing (exactly the same however, from zero to null), will this script simply swap ALL fields it finds with a zero only populated or will I need to specify field numbers?

Apologies for the questions but this is good for me to learn..

ThanksInAdvance...
