vgersh,
thanks so much for your quick response! I implemented the code and played around with it but couldnt find a way to use variables in the situation. Instead of John, Fred, Steve and bubba I need $VarFriend1, $VarFriend2, and $Varfriend3 - with these values set by the user with the previous command:
read VarFriend1 VarFriend2 VarFriend3
I seem to have trouble assigning the variable names these other variables...it just prints them as normal text.
So ideally, the code would go:
"Please enter your friends' names, seperated by spaces":
John Fred Steve (entered by user)
Then it would display these names like in the code you provided as values of $VarFriend1 $VarFriend2 and $VarFriend3.
Cheers for your help so far buddy
I've felt I've gotten a lot further so far already!

pmerr
PMERR(1) General Commands Manual PMERR(1) NAME
pmerr - translate Performance Co-Pilot error codes into error messages SYNOPSIS
pmerr code ... pmerr -l DESCRIPTION
pmerr accepts standard Performance Co-Pilot (PCP) error codes via the code argument(s) and generates the corresponding error text. Each code may be an integer, a hexadecimal value or a hexadecimal value prefixed by either ``0x'' or ``0X''. Error codes must be less than zero, so if code is a positive number, a warning message is produced, and the negated value is used. The alternative use of the -l option causes all known error codes to be listed, along with their symbolic names and error text. PCP ENVIRONMENT
Environment variables with the prefix PCP_ are used to parameterize the file and directory names used by PCP. On each installation, the file /etc/pcp.conf contains the local values for these variables. The $PCP_CONF variable may be used to specify an alternative configura- tion file, as described in pcp.conf(5). SEE ALSO
PMAPI(3), pmErrStr(3), pcp.conf(5) and pcp.env(5). Performance Co-Pilot PCP PMERR(1)
