Re^3: Does problem is in the for loop???

Update: Ignore this post, see Re^4: Does problem is in the for loop???.

Are you sure this is your code?

print OUT if ((s/m/$uut_names[$i]/) && (s/in1/$nets[$i]/) && (s/output
+/$enabled_nets[$i]/));

You say that "it is writing first element alone in XOR_portmap_nets file" but there is no output being written to file here. There are a few issues here, the tutorial Basic debugging checklist mentions three questions which you need to understand:

Are you sure your data is what you think it is?
Are you sure your code is what you think it is?
Are you inadvertently ignoring error and warning messages?

`print OUT if ((s/m/$uut_names[$i]/) && (s/in1/$nets[$i]/) && (s/output/$enabled_nets[$i]/));` there is no output being written to file here You are missing the `while (<IN>) { ... }` loop around this statement. `print` defaults to writing `$_` when called without arguments or only a file handle. Stupid demo: `>perl -E "open IN,'<','/etc/group'; open OUT,'>','/tmp/foo'; while (<I +N>) { print OUT if /adm/; } close OUT; close IN;" >cat /tmp/foo sys:x:3:root,bin,adm adm:x:4:root,adm,daemon disk:x:6:root,adm >` [download] Alexander -- Today I will gladly share my knowledge and experience, for there are no sweeter words than "I told you so". ;-)	[reply] [d/l] [select]

Doh! Indeed I am, thanks for pointing this out. Another occasion where I need to take a step back and properly regulate my caffeine/blood level.	[reply]
