What is #13#10 and #$D#$A in Delphi?
#13#10 and #$D#$A are called as control strings in Delphi which are used to set layout of a string. Both #13#10 and #$D#$A same ASCII codes and used to add new line to a string where the difference is in their representation that #13 is decimal but #$D is hexadecimal . For example, if we want to show a message having 2 lines then we can write following codes. Showmessage('First line' + #13#10 + 'Second line'); Here in above code #13#10 part represents a carriage return + line feed combination. So the message will show as following.
