Hi,
I found a problem with sacswap. Although nowadays with sac's ability
to read both big- and little-endian sac files, sacswap must be less
often used, some people I know are still using it since some of the
legacy software such as pssac [3] can only deal with big-endian sac
files.
PROBLEM:
I used sacswap on my linux system to convert a random sac file vel.sac
(little-endian) to vel.sac.swap (big-endian), and then from
vel.sac.swap (big-endian) to vel.sac.swap.swap (little-endian). By
doing…

Hi,
I just found some little things that could be improved for bin/sacinit.sh .

"export SACHOME=/usr/local/sac" may be a better general setting here.

Hi there,
I met this "WARNING: Number 4003 integer too large" when I tried to
multiply my data by a factor of 10^9, and found in the changelog that
it is a known bug.
I took a look at the corresponding code snippet in src/ucf/cnvati.c
starting from L163:
/* - Build integer from the stored digits. */
ifac = 1;
*intgr = 0;
for( j2 = j1; j2 >= 1; j2-- ){
/* -- Warning.. Approaching maximum integer size.
* - Use a fudge factor of 1…

Hi,
An equation is missing from the help file of 'envelope': sqrt(x(n)^2 + y(n)^2).
Here is the fix (I've formatted the paragraph after inserting the
missing equation):

--- aux/help/envelope.old 2008-08-28 17:33:18.000000000 -0400
