Insight would be appreciated

dear all,
In my script, it would be ideal if I could use an arc-cos (inverse cos) function. I think trig functions are indeed provided by awk, but not inverse trig functions.
So my question simply is: are there any alternative ways to incorporate inverse trig functions into a script?
Any... (2 Replies)
I learn using RS in awk to extract portion of file in this forum which is wonderful solution to the problem. However, I don't understand how exactly it operates.
I don't quite understand the mechanism behind how searching for /DATA2/ can result in extracting the whole section under "DATA2"

I wrote a very simple script to understand how to call user-defined functions from within awk after reading this post.
function my_func_local {
echo "In func $1"
}
export -f my_func_local
echo $1 | awk -F"/" '{for (k=1;k<=NF;k++) {
if ($k == "a" ) {
system("my_local_func $k")
}

IGAWK(1) Utility Commands IGAWK(1)NAME
igawk - gawk with include files
SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ...
igawk [ all gawk options ] [ -- ] program-text file ...
DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).
AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like
@include getopt.awk
in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.
OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports.
EXAMPLES
cat << EOF > test.awk
@include getopt.awk
BEGIN {
while (getopt(ARGC, ARGV, "am:q") != -1)
...
}
EOF
igawk -f test.awk
