[claudio testa]

I have set MYTEST="1 2 3" and also i have set A="MY" and B="TEST".
If i do:
1) echo ${MYTEST} the output is corretc "1 2 3"
2) echo $A$B the output is "MYTEST" but i wolud like print "1 2 3", how to do?

Thanks in advance and sorry for my poor english.

You cannot do indirect variable reference like that; the closest thing available in either bourne or korn shell scrips is an array.

[root@vpart1 /tmp]# eval echo \$${A}${B}
1 2 3
[root@vpart1 /tmp]#
