Hi,
Does it have to be CSH? I mean it may be simpler in other shell languages like PERL.

Anyway in CSH to make a array of

@ x = 1
set a = "A12"
set b = `expr length $a`
set q = ""
while ( $x <= $b )
set q = ( $q `expr substr $a $x 1` )
@ x ++
end

echo &quot; q[1] == $q[1] &quot;
echo &quot; q[2] == $q[2] &quot;
echo &quot; q[3] == $q[3] &quot;

set q = ( $q `expr substr $a $x 1` )

q[1] == A
q[2] == 1
q[3] == 2

if you don't like.....

set q = ( $q `expr substr $a $x 1` )

you could use

set q = ( $q `echo $a | cut -c $x` )


now if you actually had a desire to put the first letter in one and the rest in another


set a = &quot;A12&quot;
set b = `echo $a | cut -c 1 `
set c = `echo $a | cut -c 2- `

echo &quot;b == $b&quot;
echo &quot;c == $c&quot;

b == A
c == 12

or you could make an array


set a = &quot;A12&quot;
set b = `echo $a | cut -c 1 `
set c = `echo $a | cut -c 2- `
set q = ( $b $c )
echo &quot; q[1] == $q[1] &quot;
echo &quot; q[2] == $q[2] &quot;

q[1] == A
q[2] == 12
