This batch file list for both ways of conversions which includes files for all 30 plane slots (less them self named ckpt files that are around in some skins and such).
Example: So say you want to convert a 110c tpc file to pcx just drop all tpc files inside the "to pcx" folder and hit "110c TPC-PCX.bat" and all the files will be done, same goes for pcx back to tpc...use the "to tpc" folder
 
Also one file for Main, Config and all 3 Picplng/b/a files.
 
Both Bn & Lr Terrain files....I was going to leave out the Lr files but kept it just in case...someone finds a need. :-)
 
An additional file for Gunsights.
 
Finally one Auxiliary file for lesser used files (at least by me) such as Ground Objects and such....with this one you will have to select "Edit" and type the command in by ones self to fit the file to be converted....this is just an extra so it's there if you/I need it.
 
Just drop the files in the folder you want converted and hit the Batch file to match and your done.If there is a bigger project I will copy the batch file needed at that time into my work folder that I paint in, this also has "PicPac" and "gpmtpc2pcx" in it as well...thus I can just hit the batch file and ...BAM...The files are converted for me.

In following description "<xxx>" means "value of xxx" and "[yyy]" means "yyy is optional"

How gpmTpc2Pcx uses <inputfile> from command line:
The form of <inputfile> is:
[drive][path]basefilename[extension]

If "extension" is NOT supplied, "gpmTpc2Pcx" checks if file specified by <inputfile> (without extension for now) exists and if so, tries to use it. If not, it appends ".tpc" to <inputfile> and tries again.
If extension is supplied, "gpmTpc2Pcx" will use it whatever it is.

How gpmTpc2Pcx uses <outputfile> from command line:
The form of <outputfile> is:
[drive][path][basefilename][extension]
(So as you see the output file may not be delivered at all.)

If "outputfile" IS delivered it used without any changes. (But if it contains "path", it MUST exist. "gpmTpc2Pcx" do not create directories)
If "outputfile" is NOT delivered,"gpmTpc2Pcx" creates file with name "<basefilename>.cip". (As you see, file is created in current working directory.)

It works with ".ter", ".spt", ".mpc" files too. In fact this files are ".tpc" files whith changed extension.

				Hi
I finished second alfa version of my "gpmTpc2Pcx".
Here is an info about it:
1) This version is expected to work corectly with every ".tpc" file
except this which was saved with "-sega" option
I will correct it within a few days.
2) Only (for a while, until I learn other formats) capable
3) There are differencies in header and palette values
between an original ".pcx" file and it's unpicpacked version
To get rid of palette differencies, option "-8" in "PicPac"
must be used. In case of the header, this information is not used in
".pcx's" version 5, which is the version that "PicPac" expects
and (only) accepts, so ".tpc" does not store it.

I intend to start sending this version to anybody who sent or send me
his email after 18:00 GMT+1, when internet in my country becomes cheaper.

Other note:

When you use "-8" option "picpac" itself applies "-p" and additionally does 
NOT shifts each color value (R,G,B) left 2 bits. Simply this bits are not 
lost. 
I know what "-sega" option do by I do not know why. I can only gues that it 
has something in common with Sega console architecture which I don not know 
neither care. 
-----------------------------------------------

"gpmTpc2Pcx" always checks wether ".tpc" file it processes was compressed by 
"PipPac" with "-8" or "-p" option. In latter case, it shifts each color 
value right 2 bits, filling the lowest 2 bits with zeroes. So stated two 
lowest bits are lost only during first use of "PicPac" with "-p" option. How 
EAW uses ".tpc", I do not know. 
-----------------------------------------------

it's a "ordinary" pcx or a converted pcx file everything will work OK?

YES.
