This is a program to get the run time for the given code in the selection screen. In the selection screen you can press the "Check syntax" button to do the syntax check of the code before running to get the run time.

Code:
REPORT z_run_time_analysis.

* Data declarations.
TABLES: sscrfields.
DATA: t_code    TYPE STANDARD TABLE OF char72.
DATA: v_line    TYPE i.
DATA: s_message TYPE trmsg.
DATA: v_word    TYPE char72.
DATA: v_report  TYPE syrepid VALUE 'Z_TEST_REPORT_11'.
DATA: v_time1   TYPE i.
DATA: v_time2   TYPE i.
DATA: v_repid   TYPE syrepid.

* Container and editor.
DATA: x_docking TYPE REF TO cl_gui_docking_container,
      x_editor  TYPE REF TO cl_gui_textedit.

* Selection screen.
PARAMETERS:report(72) DEFAULT 'REPORT z_test_report_11.'.
