code eller preformatted

Hva slipper greiest igjennom, en blokk med code eller preformatted?

En code-blokk

#!/bin/awk -f

BEGIN {
printf("Status: 200 OK\n");
printf("Content-type: text/plain\n\n");

for ( key in ENVIRON ) {
print key " : " ENVIRON[key];
}
}

eller preformatted-blokk

#!/bin/awk -f

BEGIN {
printf("Status: 200 OK\n");
printf("Content-type: text/plain\n\n");

for ( key in ENVIRON ) {
print key " : " ENVIRON[key];
}
}
