Hi All, I wanted to check whether the user input is only a number and does contain any alphabet/s anywhere i.e. starting, end or in-between. Can somebody tell me how to do this?
TIA

Hey,
Please wrap your lines :-)
To match 4blabla4 you can do
if ( $line =~ m/^\d[a-z]{6}\d$/ ) to match a digit at the start of the line , 6x a till z, and a digit again but then at the end of the line.
\d = match one digit \d+ = match more digits
[a-z] match any alphabetic letter
x{6} number of occurences of x (how manytimes does x must match)^ = begin of the line $ = end of the line
Do you mean that?
