shell302a users:

I am using shell302a and am getting little response from the two folks in 
Italy when I direct questions there.  I wonder if anyone could help with a 
problem I am having...

I have immense problems piping one shell script into a second script which
uses pipes internally.  Consider the following shell302a scripts:

----snip----snip----snip----snip----snip----snip----snip----snip----snip
scripta:

echo bob stanley
echo rich walton
echo goose gossage
echo bob allen

scriptb:

cat >ram:bah
forline i ram:bah "echo $i | input a;echo $a"

----snip----snip----snip----snip----snip----snip----snip----snip----snip

Before I explain, bear in mind these accomplish nothing in particular,
besides illustrate a problem (in my mind) in shell302a.

Running scripta produces the list of names, as one would expect.

Redirecting a text file into scriptb via "scriptb <file" echos out the
file as would be expected.

Typing:

shell -c "scripta" | shell -c "scriptb"

produces a redirection error, within scriptb.  I believe scriptb is trying
to create a temporary pipe file with the same name as that used for the
pipe between the scripts.  My experiments lend data to this thoery. Other
methods, such as

scripta | scriptb

which takes automatic sourcing for granted doesn't work at all, as the
shell gets confused.

SUMMARY!  Does anyone have legally distributable source that I could modify,
or better yet an alternative method to pipe between two shell302a scripts,
where the latter uses pipes within?  Or worse yet, maybe you have seen an
error in my ways?
