[9fans] plan9 program to balance your checking account

[tad]

I got sick of trying to balance my checking account on 
paper and by hand.  It's much easier to rearrange and
fix incorrect transactions in your favorite text editor
such as acme(1) or sam(1).

So, I threw together a simple program to help me out.

You can find it at:

P.S.  It's not very efficient, but then again, I average
about one transaction per day, so it doesn't have to be.

You can use colormap to change red to blue.  :-)

The C program admittedly does more than this,
but I've been quite happy with:

g% cat balance.awk
/^#/	{ next; }
NF>=3 && $1 == "+" { total += $3; next; }
NF>=3 && $1 == "-" { total -= $3; next; }
NF>=3 && $1 ~ /^[0-9]+$/ { total -= $3; next; }
NF>=3 && $1 == "=" {
	n = total - $3;	
	if(n < -0.005 || 0.005 < n)
		printf("%s:%d: computed total %.2f expected %.2f\n",
			FILENAME, NR, total, $3);
	next;
}
{ printf("%s:%d: syntax error: %s\n", FILENAME, NR, $0); }

END{ print total }
g%

The input file is a sequence of lines of the form
	+|-|=|checknumber	mm/dd/yyyy	amount	comment
