replacing numbers greater than 0 with 1

I have some ASCII files containing numerous numbers. What I'd like to do is replace all numbers greater than 0 with 1.

Examples of the numbers include: - 000011 and 000042

Thanks

Pls show a sample file and a desired output.

OK I cant show a complete file (They are big!)

So this is a section of one of the text files

-99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 001037 001015 000946 001044 001059 001049 001074 001064 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 001053 001031 000812 000993 000663 001089 001071 000994 001066 001099 001104 001073 000959 000982 001062 001039 001020 001041 001071 001020 001041 000972 000941 000944 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999 -99999

Basically I want to ignore the -99999's and convert all other numbers EQUAL OR GREATER THAN 0 (I apologise I didn't put the EQUAL in before!) to 1.

Thanks

something along these lines:

nawk '{for(i=1; i<=NF; i++)  $i=($i>=0) ? 1 : $i}1' myFile

Thanks vgersh99 that works very well

thank you
