I have tried this workaround (even if I see it as a defiance :-) ).
but another problem arised: i want to keep the control in the main script of the variable to be passed so I would like to pass them to the script.
this is the "inner" script:
#!/bin/sh
# loop through a set of numbers
# echo $pt
echo nome$1
echo pt$2
echo eta$3
for i in 1 2 ;
do ../herlib/hwuser<<stop ;
$1
$2 $3
$i
stop
done
when I do
$ ./forloop a b c
it works but when it is called by another script it fails to recognize the variables.
for example: I call the previous script (forloop) through
name=tt_25_5_0jet
pt=20
eta=0.6
./forloop<<stop
$name
$pt
$eta
stop
but don't work... any idea?
THANKS in advance Michele

echo(1B) SunOS/BSD Compatibility Package Commands echo(1B)
NAME
echo - echo arguments to standard output
SYNOPSIS
/usr/ucb/echo [-n] [argument]
DESCRIPTION
echo writes its arguments, separated by BLANKs and terminated by a NEWLINE, to the standard output.
echo is useful for producing diagnostics in command files and for sending known data into a pipe, and for displaying the contents of envi-
ronment variables.
For example, you can use echo to determine how many subdirectories below the root directory (/) is your current directory, as follows:
o echo your current-working-directory's full pathname
o pipe the output through tr to translate the path's embedded slash-characters into space-characters
o pipe that output through wc -w for a count of the names in your path.
example% /usr/bin/echo "echo $PWD | tr '/' ' ' | wc -w"
See tr(1) and wc(1) for their functionality.
The shells csh(1), ksh(1), and sh(1), each have an echo built-in command, which, by default, will have precedence, and will be invoked if
the user calls echo without a full pathname. /usr/ucb/echo and csh's echo() have an -n option, but do not understand back-slashed escape
characters. sh's echo(), ksh's echo(), and /usr/bin/echo, on the other hand, understand the black-slashed escape characters, and ksh's
echo() also understands a as the audible bell character; however, these commands do not have an -n option.
OPTIONS
-n Do not add the NEWLINE to the output.
