Compound Variables
The Korn shell also supports compound variables, which are similar to structures or records in other languages, that is a meta-datatype which is a group of related values, each of which can have a different data type. The syntax for declaring compund variables is:
compound_variable=( [datatype] field1[=value] . . . [datatype] fieldn[=value] )
For example, we can use a compound variable to manage employee information:
$ employee=( typeset name=Allenby integer id=1243 float salary=9000.50 )
The syntax to display the value of a compound variable field is:
${compound_variable.field}
Here we access the employee compound variable:
$ print $employee
( typeset -E salary=9000.5 name=Allenby typeset -i
id=1243 )
$ print ${employee.name}
Allenby
