Perhaps you should try some spelling variations:
"programable al codigo." » "programable plc codigo." (Expand Search), "programables en codigo." (Expand Search), "programables bajo codigo." (Expand Search), "programable del codigo." (Expand Search)
"programacion a codigo." » "programacion _ codigo." (Expand Search), "programacion de codigo." (Expand Search), "programacion en codigo." (Expand Search), "programacion el codigo." (Expand Search)
"programas _ codigo." » "programa _ codigo." (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"programas _ codigo.\") OR (\"programable al codigo.\"))) OR (\"programacion a codigo.\"))~".
• Removing quotes may allow a broader search: (((( programas _ codigo. ) OR ( programable al codigo. ))) OR ( programacion a codigo. ))~.
• Adding a wildcard symbol may retrieve word variants: (((("programas _ codigo.") OR ("programable al codigo."))) OR ("programacion a codigo."))*.
