OK.... I got it.  But just to confirm... this works:

#!/bin/bash
export MYARG=$1
topaz -l <<EOF
set gems seaside user DataCurator pass swordfish
login
printIt
'The first argument was: ', (System performOnServer: 'echo $MYARG').
%
login
printIt
'$1' printString
%
exit
EOF

and run it "sh runTopaz.sh mariano"

but if we move the topaz script to a separate file and we do the input...it
doesn't work anymore:

#!/bin/bash
export MYARG=$1
topaz -l <<EOF
input test.tpz
EOF

"sh runTopaz.sh mariano"

and test.tpz being:

set gems seaside user DataCurator pass swordfish
login
printIt
'The first argument was: ', (System performOnServer: 'echo $MYARG').
%
login
printIt
'$1' printString
%
exit

so the only way to get it work is to embed the topaz script inside the bash
script right? (like the first example)

Ok...if I embed the topaz script in the bash (not using input) I can access
both, parameters and exported variables, from both, topaz and smalltalk.
If I don't embed the topaz script (use input), then, I cannot access any
variable either from topaz or smalltalk.

so...this is the expected behavior right?

You right, I missed that difference. You right, it's not the same case.

Thanks a lot Ralph for your help, it is really appreciated.
