An excess of caution would suggest adding a defined test to the `while`-loop conditional. This test is not added by default by the compiler in the case of a complex conditional expression like the `do`-block: `while ( defined($_ = do { ... }) ) { ... }` Give a man a fish: `<%-{-{-{-<`	[reply] [d/l] [select]

Yes, good practice does require the 'defined'. In this application, I am already assuming the format of a 'block'. The special case (block is defined, but evaluates to FALSE), which requires 'defined', should never happen. Bill	[reply]

Hello, Thanks a lot for your response and is working fine for the fixed format given before. Now I have a situation where I may get somehting like this &LOG &LOG TEXT: "C:\temp\xyz.txt" &LOG Action: DEFAULT &LOG Naming_Technique: DEFAULT_NAMING Default_Name: @ST/ABC1234/00001 &LOG Container: "current:entity" &LOG Type: SIMILAR &LOG Name: ABC-Y &LOG Description: ABC-Z &LOG Associated_Files_Directory: "" &LOG &LOG TEXT: "C:\temp\PQR.txt" &LOG Naming_Technique: USER_NAME Default_Name: @ST/ABC9999/00001 &LOG &LOG &LOG TEXT: "C:\temp\abc.txt" &LOG Action: DEFAULT &LOG Naming_Technique: DEFAULT_NAMING Default_Name: @ST/ABC5678/00001 &LOG Container: "current:entity" &LOG Type: SIMILAR &LOG Name: EWQ-Y &LOG Description: EWQ-Z &LOG Associated_Files_Directory: "" &LOG &LOG TEXT: "C:\temp\rtq.txt" &LOG Action: DEFAULT &LOG Naming_Technique: DEFAULT_NAMING Default_Name: @ST/ABC2345/00002 &LOG Container: "current:entity" &LOG Type: SIMILAR &LOG Name: ERD-Y &LOG Description: ERD-Z &LOG Associated_Files_Directory: "" &LOG [download] Here I do not want PQR.txt and its number ABC9999 in the output. Difference here is that, whenever I have USERNAME after Naming_Technique, i should avoid its .txt and number in the output. So my output remains same as before `[xyz.txt] db_part_no=ABC1234 db_part_rev=00001 [abc.txt] db_part_no=ABC5678 db_part_rev=00001 [rtq.txt] db_part_no=ABC2345 db_part_rev=00002` [download] could you please help?

I am sorry my mistake. Now I correct the input file.. The one with PQR.txt also starts with TEXT and not Part.	[reply]

You are of course assuming that the Associated_Files_Directory field will always be equal to "" and that it will always be the last field in the record.	[reply]
