Thanks Perderabo. I did two different commands (one to create a directory which I realized may have been a problem other than the 'limit' on command line) but both errored by beeping constantly and giving an error in the middle of the line.
On one, it cut a grep command and came back with "command not found" for "rep" and the other died along the same line (same number of characters).
cat passwd | grep h | grep o | grep m | grep e | grep a | grep i | grep o | grep 8 | grep 1 | grep 3 | grep 2 | grep 9 | grep "-" | grep S | grep b | grep l | grep t | grep L | grep 4 | grep d | grep r | grep 0 | grep V | grep I | grep abal | grep k | grep and | grep ers | grep eit | grep N | grep z | grep w | grep g | grep N
$ V | grep I | grep abal | grep k | grep <
usage: grep [-E|-F] [-c|-l|-q] [-bhinsvx] -e pattern_list...
[-f pattern_file...] [file...]
usage: grep [-E|-F] [-c|-l|-q] [-bhinsvx] [-e pattern_list...]
-f pattern_file... [file...]
usage: grep [-E|-F] [-c|-l|-q] [-bhinsvx] pattern [file...]
Note that when hitting return, it errors and gives back a prompt and includes the rest of the line as a start of a new command ($ V | grep 1 ....).
This is probably some other parameter set differently from one system to the next (or possibly shell) but I figured I would ask about it. I can also get the same response on Solaris even though I found some indication that the same information you suggested was true for it too. Ksh on HP and csh on Solaris. And for some reason I get a few more characters (about 40 ) on Solaris. The whole thing is strange and inconsistant.

when sending the contents of a ascii file to the body of an email then sending it off. it seems sendmail is breaking up the lines with a "!" thus ruining the data. Has this ever happened to anyone?

ZGREP(1) General Commands Manual ZGREP(1)
NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code:
(-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the
standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep.
If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.
EXIT CODE
2 - An option that is not supported was specified.
