Just as grammatical rules are used for the spoken language, PPCL uses rules to create commands and instructions. Each PPCL program must conform to these rules; otherwise, the computer will not understand what you are trying to say.

  • Program lines are executed in ascending order according to their line numbers, unless directed otherwise.
  • When the last line of the program is reached, the computer automatically returns to the first line of the program and continues processing.
  • Any program line that begins with C must be enclosed by parentheses ( ).
  • PPCL statements that do not follow the correct structure may produce unexpected results.
