Tom, I saved some of the floaters products on zero, ~ldm/data/radar. These products have 2 extras nulls at the end so they have different md5 checksums. ie. ... ... 0102220 327 020 W 347 020 W 027 \0 310 l 233 372 \r \r \n 003 0102240 \0 \0 Hopefully your decoder can handle the extra chars. Also are the file names in a usable format? The pqact entry: # save FLOATER NMC3 ^FLOATER SDUS5. .... ([0-3][0-9])([0-2][0-9])([0-5][0-9]) /p(......)
