OPEN, CLOSE, and INQUIRE Keywords

g77 doesn't have support for keywords such as DISP='DELETE' in the OPEN, CLOSE, and INQUIRE statements. These extensions are easy to add to g77 itself, but require much more work on libg2c.

g77 doesn't support FORM='PRINT' or an equivalent to translate the traditional `carriage control' characters in column 1 of output to use backspaces, carriage returns and the like. However programs exist to translate them in output files (or standard output). These are typically called either fpr or asa. You can get a version of asa from ftp://sunsite.unc.edu/pub/Linux/devel/lang/fortran for GNU systems which will probably build easily on other systems. Alternatively, fpr is in BSD distributions in various archive sites.
