i've got a whole file to scan...but can't get neatly get the last
occurance with...
.scan(/(^A.*?)^A/m){|a| stops<<$1} ...yes i know that last occurance
is not scanned
because it is succeeded with ^Z line....that's the complication....
A......
M.....
d....
A....
r....
f....
A....
.... etc to the last A group....
A.....
c....
t....
Z.....

note each ^A group can end only with a new occurance of another A
record or the Z record.which
is the last record of the file....So? how do make a more eligant Reg
expression to cover this
situation?

Hope there is one solution O.K. for you.

>>>>> Code >>>>>

mylines = <<EOT
A......1
M.....
d....
A....1
r....
f....
A.....1
c....
t....
Z.....
EOT
puts '########## Without last Z-Record ##########'
mylines.scan(/^A.*?(?=^(?:A|Z))/m){|a|puts "#{a}\n----------"}
puts '########## Last Record up to EOF ##########'
mylines.scan(/^A.*?(?=^A|\Z)/m){|a|puts "#{a}\n----------"}
puts '########## Includings last Z-Record ##########'
mylines.scan(/^A.*?(?:(?=^A)|^Z.*$)/m){|a|puts "#{a}\n----------"}

>>>>> Results >>>>>

########## Without last Z-Record ##########
