Can you talk me through that sed command - with a slight edit I "think" I get what I want:

Code:
> sed 's:\(^THIS[^ ]* \) :\00:' file

Specifically the 10, which I replaced to 00... - simply adds a space followed by a 0 to the location I require.

fixadd(3alleg4) 						  Allegro manual						   fixadd(3alleg4)

NAME
fixadd - Safe function to add fixed point numbers clamping overflow. Allegro game programming library. SYNOPSIS
#include <allegro.h> fixed fixadd(fixed x, fixed y); DESCRIPTION
Although fixed point numbers can be added with the normal '+' integer operator, that doesn't provide any protection against overflow. If overflow is a problem, you should use this function instead. It is slower than using integer operators, but if an overflow occurs it will set `errno' and clamp the result, rather than just letting it wrap. Example: fixed result; /* This will put 5035 into `result'. */ result = fixadd(itofix(5000), itofix(35)); /* Sets `errno' and puts -32768 into `result'. */ result = fixadd(itofix(-31000), itofix(-3000)); ASSERT(!errno); /* This will fail. */ RETURN VALUE
Returns the clamped result of adding `x' to `y', setting `errno' to ERANGE if there was an overflow. SEE ALSO
fixsub(3alleg4), fixmul(3alleg4), fixdiv(3alleg4) Allegro version 4.4.2 fixadd(3alleg4)
