ADDRESS CONTENT VARIABLE csh

Comment:

By using a csh, I want to address a variable content whose name is/matches the content of a given other variable. i.e. set name=´sam´ set ${name}_age=´27´ So, by typing: echo ${name}_age I correctly obtain: sam_age By typing: echo $sam_age or echo ${sam_age} I correctly obtain: 27 But how can I obtain "27" by using ${name} instead of "sam"? The following instruction does not work! echo ${`echo ${name}_age`} Any helps will be accepted! Thanks a lot!

The eval command is typically used for this: #!/bin/csh set name='sam' set eval ${name}_age='27' echo "sam is: ${sam_age}"
