This is useful to allow further arguments to the +AWK program itself to start with a ``\-''. +This is mainly for consistency with the argument parsing convention used +by most other \*(PX programs. +.PP +Following the \*(PX standard, +.IR gawk -specific +options are supplied via arguments to the +.B \-W +option. Multiple +.B \-W +options may be supplied, or multiple arguments may be supplied together +if they are separated by commas, or enclosed in quotes and separated +by white space. +Case is ignored in arguments to the +.B \-W +option. +.PP +The +.B \-W +option accepts the following arguments: +.TP \w'\fBcopyright\fR'u+1n +.B compat +Run in +.I compatibility +mode.

This is useful for building libraries +of AWK functions, without having to include them in each new AWK |
