There seem to be a few problems in your sample input files.

You imply that both of your input files use comma as your field separator, but the OCD3 in File1 is not the same as OCD3 followed by more than 20 spaces in File2.

Is there really supposed to be a space at the start of line 3 in File2?

The code that you said works (but you want something better for larger files), produces the output:
Code:
000433,ds00d11,tdev,ds00d11_view,0CD3,000433,0CD3                            
000566,114D                          
000433,ds00d12_34,tdev,ds00d12_view,132D,000566,114F

for the sample input you provided; not what you said you wanted:
Code:
000433,ds00d11,tdev,ds00d11_view,0CD3,CG01_ds00d11_drs,000566,114D
000433,ds00d12_34,tdev,ds00d12_view,132D,CG02_ds00d12_34_drs,000566,114F

The following awk script seems to do what you want:
Code:
awk '
BEGIN {	FS = ",| *$"
	OFS = ","
}
NR == FNR {
	data[lf[$4] = $2] = $1 OFS $3 OFS $4
#printf("in: %s\ndata[lf[%s](%s)]: %s\n", $0, $4, lf[$4], data[lf[$4]])
	next
}
{	print $0, data[lf[$5]]
}' File2 File1

If you want to try this on a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk. With your sample input files, the above code produces the output:
Code:
000433,ds00d11,tdev,ds00d11_view,0CD3,CG01_ds00d11_drs,000566,114D
000433,ds00d12_34,tdev,ds00d12_view,132D,CG02_ds00d12_34_drs,000566,114F

which seems to be an exact match for what you said you wanted.

ppmtosixel

ppmtosixel(1)						      General Commands Manual						     ppmtosixel(1)

NAME

       ppmtosixel - convert a portable pixmap into DEC sixel format

SYNOPSIS

       ppmtosixel [-raw] [-margin] [ppmfile]

DESCRIPTION

       Reads  a  portable  pixmap  as input.  Produces sixel commands (SIX) as output.	The output is formatted for color printing, e.g. for a DEC
       LJ250 color inkjet printer.

       If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled.  A printer control header and a color assignment table
       begin the SIX file.  Image data is written in a compressed format by default.  A printer control footer ends the image file.

OPTIONS

       -raw   If  specified,  each  pixel  will  be explicitly described in the image file.  If -raw is not specified, output will default to com-
	      pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands.  A raw file is often an order	of  magni-
	      tude larger than a compressed file and prints much slower.

       -margin
	      If  -margin  is not specified, the image will be start at the left margin (of the window, paper, or whatever).  If -margin is speci-
	      fied, a 1.5 inch left margin will offset the image.

PRINTING

       Generally, sixel files must reach the printer unfiltered.  Use the lpr -x option or cat filename > /dev/tty0?.

BUGS

       Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion.  If the original PPM maxval was
       greater	than  100,  rescaling  also reduces the image depth.  While the actual RGB values from the ppm file are more or less retained, the
       color palette of the LJ250 may not match the colors on your screen.  This seems to be a printer limitation.
