 korn shell variable in variable access
Hi,

i try to get the content of a variable from a variable.
ie

VAR1="var1_content"

n=1

build VAR2 using the string "VAR" and the value of n
VAR2=VAR$n

How can i get "var1_content" using VAR2 ?

$VAR2 => VAR1 !!
${$VAR2} => KO !!!
should i change VAR2 construction

thanks

In article <cada658b.0406030149.1ed72...@posting.google.com>,

eval 'echo $VAR'$n

However, it's likely that arrays will solve your problem more cleanly.
