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
