The Assembler I used in the early days of my programming life had a limit of 8 characters name. We had a naming standard that the first 2 characters of the variable name described the data type which left 6 characters for the descriptive part of the variable name. This naming convention was carried to other modules used across various programs.
ST stood for Standard Table (a shared table that was centrally maintained and could be accessed by any application). One day we were asked to create a new standard table for a list names of Credit Unions. We had to come up with a name and definition to put to the committee that approved the shared modules. The front runner was "Credit Union Name Table".
The standards review board rejected the name. :)
