[fpc-pascal] Pascals unit for associate arrays?

[Francisco Reyes]

Is there any unit, or built in functionality, to do the equivalent of 
perl's associate arrays or Python's dictionaries?


What I am trying todo is to parse some lines and to store ocurrences of 
certain strings.

For example
string1
string2
string1
string3
string2

What I want to do is to create an entry string1 and count all string1 one 
ocurrences, the same for each different string. In the end I would have
string1 2
string2 2
string3 1
