Ah, so apparently it only works with the ~ "contains" operator, not == and !=, etc:

Code:
> cat datafile
Bob  here
Jane here
Ron  absent
Linda absent
Paul unknown

> awk '$1 ~/Bob|Linda/ {print $0}' datafile
Bob  here
Linda absent

> awk '$1 == /Bob|Linda/ {print $0}' datafile

> awk '$1 != /Bob|Linda/ {print $0}' datafile
Bob  here
Jane here
Ron  absent
Linda absent
Paul unknown

That's a shame, but it's more than I had before. Thanks for the reply.

load_datafile(3alleg4)						  Allegro manual					    load_datafile(3alleg4)

NAME
load_datafile - Loads a datafile into memory. Allegro game programming library. SYNOPSIS
#include <allegro.h> DATAFILE *load_datafile(const char *filename); DESCRIPTION
Loads a datafile into memory in one go. If the datafile has been encrypted, you must first call packfile_password() to set the appropriate key. If the datafile contains truecolor graphics, you must set the video mode or call set_color_conversion() before loading it. Example: /* Load the resources for our game. */ DATAFILE *dat = load_datafile("game.dat"); if (!dat) abort_on_error("Couldn't load sound resources!"); /* Use resources. */ ... /* Destroy them when we don't need them any more. */ unload_datafile(dat); RETURN VALUE
Returns a pointer to the DATAFILE, or NULL on error. Remember to free this DATAFILE later to avoid memory leaks. SEE ALSO
