Editing Tandy Pocket Computer (section)

===Run===
In Run mode, the [[command line]] could be openly used to execute one-line, non-BASIC operations. This is the normal mode used, from where arbitrary [[calculation]]s could be entered to receive results. The Run mode also allowed the [[execution (computers)|execution]] of the BASIC programs stored in the device.

Instead of an "equals" key to initiate calculation evaluation, an "EXE" (execute) key was provided. This caused confusion with those who were used to traditional calculators. The = character was used only for variable [[assignment (computer science)|assignment]], and evaluation tests in programs.

The input of simple calculations would be aggregated on the command line, and no results would be displayed until the EXE key was pressed. In some models, a special ANS variable was provided to reuse the results of the previous calculation; in others, the previous calculation was automatically included if the next calculation began with an operator.

Some valid calculation input examples (PC-8):

  SIN40
  10+2+(8*1)/7
  TAN (LOG (√(4/3)))
