What is the difference between "'" and "`" in character strings?
The single quote character(') in character strings do not preserve white spaces at the end whereas the "`" character preserves white spaces as it is.
Eg.:
DATA v_char(32) TYPE c.
v_char = 'This is a'.
CONCATENATE v_char 'text ' INTO v_char SEPARATED BY space.
*" v_char would be "This is a text"
CONCATENATE v_char `text ` INTO v_char SEPARATED BY space.
*" v_char would be "This is a text "
