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}


in HP/ksh not work....


and this :

$ typeset -AE exchange_rate
$ exchange_rate["DM"]=1.7
$ exchange_rate["FF"]=.15
$ exchange_rate["AS"]=.04
To display a list of associative array subscripts:
${!variable[*]} or ${!variable[@]}

not work ???
