Hi.

lst = {1, 2, 3, 4, Table[-999.99 , {19}], 5, 6, 7, 
8};

lst /. {a___, {(-999.99) ..}, b__} :> {{a}, {b}}

| hi!
|
| COuld somebody please tell me how can I do this 
in Mathematica: I have
| a file of numbers containing -999.99 in places 
where there is missing
| data.
| I want to split the file into a number of files 
based on the criterion
| that the number of consecutive - 999.99 are more 
than 18 .
|
| For example... if the file is of the form
|
| {1,2,3,4,{-999.99 repeated 18 or more 
times},5,6,7,8}
| then I want the output to be file1.txt which 
contains {1,2,3,4} and
| file2.txt which contains {5,6,7,8}
|
| Thanks,
|
| Raj
