Okay, I see. Your error-recovery is to recurse. BAD IDEA. When the code detects a bad input, it should re-start a loop, NOT re-call the function. In re-calling the function, you do not terminate the loop, so after the re-call completes, the first call of the function continues right there and adds to HI_HOSTS again.
Welcome to the pitfalls of global variables and recursion.
It should be like this:
Code:
# pseudo code
valid-input=false
while ! valid-input
prompt
get input
for each hostnum
if hostnum is invalid
invalid-hosnum=TRUE
echo "hostnum doesn't match"
else
hosts=$hosts + $hostlist[ hostnum ]
if invalid-hostnum
echo Please try again
else
valid-input=TRUE
return $hosts

Passing a array to a function, a basic feature in modern language, seems to be only possible in KSH. Not in BASH. Depite all my efforts I couldn't come to a solution. See the following examples:
It works perfectly in KSH:

Hello!
I have a question about loops and arrays. I'm trying to go through this:
for aa in 01 02 03
OrigNum=$(grep ${Orig} Ba3In2F12.prepos | wc -l)
OrigNum=$((${OrigNum} - 1))
echo ${OrigNum}
etc
It gets stuck on the second line. The error reads:

Hi,
I'm trying to write a function that reassigns an array to
another local array but the method used in reassigning
the array reformats the contents of the array which is
what I am trying to prevent.
The method used to load a file into an array works as
expected and the entire array is... (4 Replies)

There was a small bug in the Quick Editor function in postbit, but I fixed it (basically a double quote was missing from an element id):

rbash
RBASH(1) General Commands Manual RBASH(1)NAME
rbash - restricted bash, see bash(1)RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is
used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow-
ing are disallowed or not performed:
o changing directories with cd
o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV
o specifying command names containing /
o specifying a file name containing a / as an argument to the . builtin command
o specifying a filename containing a slash as an argument to the -p option to the hash builtin command
o importing function definitions from the shell environment at startup
o parsing the value of SHELLOPTS from the shell environment at startup
o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators
o using the exec builtin command to replace the shell with another command
o adding or deleting builtin commands with the -f and -d options to the enable builtin command
o using the enable builtin command to enable disabled shell builtins
o specifying the -p option to the command builtin command
o turning off restricted mode with set +r or set +o restricted.
These restrictions are enforced after any startup files are read.
When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
