Editing TELCOMP (section)

==Commands==
A TELCOMP program was made up of numbered lines, each line referred to as a Step.  Steps were grouped into Parts.  Each line contained one instruction.

  DO PART   Execute all of the steps in a numbered part and then return
  DO STEP   Execute a single line and return
  DONE      Stop execution of current part and return to caller
  IF        Condition, suffixed to any instruction
  FOR       Loop, suffixed to any instruction
  PLOT      Type output to the teletype in the form of a graph
  PRINT     Print output to the teletype
  READ      Read input from the paper tape reader
  SEND      Send output to the paper tape punch
  SET       Assign a variable to the value of an expression
  STOP      Stop execution completely
  TO PART   Go to a specified part
  TO STEP   Go to a specified line
  TYPE      Emulate teletype input while in stored operation mode (like the [[Expect|TCL/TK Expect]] functionality)
  ;         Comment, suffixed to any line
  FORM      A specification for formatted output (not really a command)
