by executing the code below

local ptrn = '\n([%d%p]+)\n'
for val1, val2 in string.gmatch(Amount, ptrn) do

    print ("val1:=\t" .. (val1 or '').."\tval2:=\t"..(val2 or ''))

end

basically from the above string I want to fetch the last 5 digits of the string which is 00564 in val1 and the amount which is 0,1234 in val2 variable, but all this should in one pattern. This is a record, every record is starting with a number like this is 1 record or row

1 CDABCDEFGHIJ00564
    0,1234

and this is 2nd record or row and so on

 2 CDABCDEFGHIJ00565
    0,0361

plese help….

    It seems to me that %d+%s+%a+(%d+)\n%s*([%d,]+) should do the trick: the first %d+ will catch the row number, %s+ to match the white space after. %a+(%d+) will match CDABCDEFGHIJ00592 and capture the digits in the end (no way to specify that you want exactly five digits though). \n%s* will match the newline and any white space on the next line and ([%d,]+) will capture the last number with the comma.
