Der Microsoft FORTRAN Compiler (Version 2.2 von 1986) kommt mit einer umfangreichen Dokumentation im Ringbuchschuber daher. Die Schreiber beweisen einen eigenen Humor:
Abschnitt über Compiler-Optionen:
2.2.6 Card Number Display at Compile Time
Selecting the D option causes the compiler to display the card number of the statement it is processing during passes 1 and 2. During pass 3 it will display the symbolic name of the program unit it s linking.
The D option is primarily a compiler debugging tool: it indicates the card number of the statement where the compiler choked. However, many users swear that the compiler runs faster with card numbers flashing by.
