The structure of a TE program is as follows:

{ declaration_block }

main

    { statement_block }

endmain

{ function_block }

All programs must have a main…endmain block and include optional decaration_block, statement_block and function_block.   

The smallest and most useless (but syntactically correct) program is the following:

   // Totally useless but syntactically correct

   main

   endmain
