Lua followed SOL (Simple Object Language) and DEL (data-entry language). They are computer languages that described and managed data. They had been independently developed at Tecgraf for two different projects. These projects were for engineering applications for the Petrobras company. Petrobras later wanted more power in SOL and DEL. They lacked functions to control flow.
