You can use the Pretty Printer function to improve the layout of your program. This function arranges associated key words in groups and indents individual statements clearly. The Pretty Printer ensures that your program layout meets the guidelines described in the ABAP User's Guide. The Pretty Printer:

• Places event, control, and INCLUDE key words on separate lines.
• Moves event key words, FORM statements, and MODULE statements to the beginning of the line. In this case, the Pretty Printer function uses the first program line as a reference.
• Inserts a blank line before event key words that are not preceded by a blank or a comment line.
• Indents all command lines and control structures associated with an event by 2 spaces.
• Locates commands that extend beyond one line and writes subsequent commands on a new line.
• Inserts appropriate comment blocks before FORM and MODULE statements that do not have comments. The Pretty Printer function uses the routine name and the USING parameter to fill in the comment blocks.
• Left-justifies comments that appear in command lines. Left-justification is only performed on comment lines of 32 characters or less that begin with " (double-quotes). Pretty Printer starts the comment at column 40.

If you have an error in your syntax, the Pretty Printer function cannot allow for it. For this reason, do not use the Pretty Printer before carrying out a syntax check. Using the Pretty Printer with incorrect syntax can lead to unpredictable results.

You should also ensure that key words, field names, variables and other program elements do not extend beyond the end of one line. Since the Pretty Printer works one line at a time, it may move parts of words but does not join them together.

You can use the Shift function to indent code. To use this feature, position your cursor on the line at the point to which you want to indent the code:

Then, press Shift to shift the text to the current cursor position:
