Another thing you can do to speed it up is keep it running - feed it input and read it output at need, rather than starting and killing it all the time. How to do that depends on what your input data would look like and what you'd want for your output data.
There is one error and corrected for the correct results, note the minus sign in red: SUMIMAG += -REAL_ARRAY[T]*SIN_ANGLE + IMAG_ARRAY[T]*COS_ANGLE;
Correct results:
Otherwise phenominal.
Thanks a lot...
(This has taught me more about awk than ANY tutorial or info from the mighty WWW and for that I can only say thank you.)

Any means of running ksh93 in a ksh88-mode?
Might sound odd, but I want/need to restrict U/Win-developed scripts to correspond to the ksh88 version on my Solaris environment(s). Thanks. (2 Replies)

Hi,
I have a script that, basically, has two input files of this type:
file1
key1=value1_1_1
key2=value1_2_1

...
file2
key2=value2_2_1
key2=value2_2_2

The keys are strings that don't... (7 Replies)

99 7372
83 175
I only wish to retain lines where the numbers fullfil two requirements. E.g:
=83
1000<=<=2000
To do this I use the following... (10 Replies)
Hi Experts,
I have several shell scripts that have been developed on a Linux box for korn ksh93.
If we want to run this software on an AIX 6.1 box that runs ksh88 by default can we just change the she-bang line to reference /bin/ksh93 which ships with AIX as its "enhanced shell" to ensure... (6 Replies)
I don't know if anyone is interested but I have been meddling with FFT for the AMIGA.
(Sadly we AMIGAns don't have these luxuries through any scripting language.

Hi everyone !

Thanks for your support and have a nice day ! (2 Replies)
Hi guys...
This is code that was originally designed to work on an upgraded AMIGA A1200 using Python 2.0.x.
Unfortunately it broke inside much later versions, NOT because of the print statement/function but other minor subtleties. So this is the final result tested on various machines including... (0 Replies)
