Command-line options

Command-line options may be put, one per line, into the initialization file .fweb (which is always in the user's home directory). In that file, options beginning with a hyphen are processed before the command-line options (so command-line options can override the defaults). To force an option to be processed after the command-line options, preface it with an ampersand rather than a hyphen; this is rarely necessary.

To make sense of the plethora of options, it helps to know that options beginning with n are related to FORTRAN; those beginning with r are related to RATFOR. Some flags that can be set separately for those two languages also have a global option that sets the flags for both languages simultaneously; cf. -n/, -r/, and -/.

Some options take arguments. For example, an FWEB macro can be defined from the command line by saying something like -mIBMPC=1. Unlike many UNIX utilities, no spaces are allowed between any option and its argument. For example, if one says -m IBMPC, FWEB will think that IBMPC is a file name.
