7.12 MKID Operator

In many applications, it is useful to create a set of identifiers for naming objects in a consistent manner. In most cases, it is sufficient to create such names from two components. The operator MKID is provided for this purpose. Its syntax is:

MKID(U:id,V:id|non-negative integer):id

for example

        mkid(a,3)      -> A3  
        mkid(apple,s)  -> APPLES

while mkid(a+b,2) gives an error.

The SET statement can be used to give a value to the identifiers created by MKID, for example

        set(mkid(a,3),3);

will give A3 the value 2. Similarly, the UNSET statement can be used to remove the value from these identifiers, for example

        unset(mkid(a,3));
