Re^4: Splice an array into another array

[Smeb]

Could you explain this code a bit?  @DNA3=split('',join('',@DNA3)); I don't quite get what it means and why this is necessary for my script to work.

[AnomalousMonk]

@DNA3 = <DNA3handle>;  # read all LINES of file into array
chomp @DNA3;           # remove any and all newlines
@DNA3=split('',join('',@DNA3));  # join('',@DNA3)  join all LINES into
+ one long line
                                 # split('', ...)  split long line int
+o list
                                 #                 of individual chara
+cters
                                 # @DNA3= ...      assign list of indi
+vidual
                                 #                 characters to an ar
+ray

@DNA3 will end up looking something like  ('A', 'T', 'C', 'G', ...) See chomp, join, split.

Update: Fixed up formatting of long comment lines for last statement.
