Extract records by column value - file non-delimited

the data in my file is has no delimiters. it looks like this:

H52082320024740010PH333200612290000930 0.0020080131

D2210007150354000120090728200907310100 4.00

In a nutshell I am trying to extract all Header Records (H in column 1) that have an amount (high-lighted in red) greater than 0.00. The field actually starts in column 39 but space fills to the might significant digit, so the '0.00' is really ' 0.00'. In this example I would only want to see the 2nd header record because its amount is 100.00.

Please help. I have been searching posts all day trying to find an awk/nawk/sed/grep, something in VI, anything.

# 2  
awk '/^H/&&substr($0,39,2)!=" 0"' infile

sed '/H/!d;/.\{38\} 0/d' infile

Try this

$ grep ^H file | awk '$3 ~ '/^[1-9]/' {print $3}'|cut -c1-6

Thanks everyone. It worked like a champ.
