Hi
Are you sure you are running your script in csh? Because 'set -x' will throw an error in csh since 'set' should follow a variable name.
It looks to be it is some other shell such as ksh/sh, which is why on doing 'set -x', it went into debug mode, and on giving 'set a = 10', it did not set 10 to a, instead it made the string 'a=10' as a command line argument($1).
Guru.

i.e.

set ${name}_age=´27´
So, by typing: echo ${name}_age
I correctly obtain: sam_age
By typing: echo $sam_age
or echo ${sam_age}
