Yes, I forgot that print$0 is the default action.
Can you tell whether !(FNR in a) is any better than !a[FNR] performancewise?

XkbFreeGeomRows(3)						   XKB FUNCTIONS						XkbFreeGeomRows(3)

NAME
XkbFreeGeomRows - Free rows in a section SYNOPSIS
void XkbFreeGeomRows (XkbSectionPtr section, int first, int count, Bool free_all); ARGUMENTS
- section section in which rows should be freed - first first row to be freed - count number of rows to be freed - free_all True => all rows are freed DESCRIPTION
Xkb provides a number of functions to allocate and free subcomponents of a keyboard geometry. Use these functions to create or modify key- board geometries. Note that these functions merely allocate space for the new element(s), and it is up to you to fill in the values explicitly in your code. These allocation functions increase sz_* but never touch num_* (unless there is an allocation failure, in which case they reset both sz_* and num_* to zero). These functions return Success if they succeed, BadAlloc if they are not able to allocate space, or BadValue if a parameter is not as expected. If free_all is True, all rows are freed regardless of the value of first and count. Otherwise, the number of rows specified by count are freed, beginning with the row specified by first in the specified section. RETURN VALUES
Success The XkbFreeGeomRows function returns Success when there are no allocation or argument errors. DIAGNOSTICS
BadAlloc Unable to allocate storage BadValue An argument is out of range X Version 11 libX11 1.6.0 XkbFreeGeomRows(3)
