Why we need to put two quotes ' ' to get a single displayed quote.

whatever u give in double quotes, it ll come as like as it is. that is considered as a string.

OTHERWISE ABAP WILL TREAT THAT STRING IS END WITH THAT....

FOR EXAMPLE....

'JEYA'SHREE'.

IN THE ABOVE STRING...ABAP TREAT THAT STRING ALREADY ENDED WITH 'JEYA'....

TO AVOID THIS....'JEYA''SHREE'.

string funcation used for quotes.

string literal,char num. all give quotes ' '

write 'hello' .-> hard code.

IN ABAP LANGUAGE '' SINGLE QUOTE MEANS IT WILL DISPLAY A STRING SAME AS IN C WE USE " "

IF YOU WRITE ' ' THEN ABAP TREATS THAT TOTAL CHARACTERS INTO THE STRING FORMAT

IF YOU DON'T GIVE 2 AND IF YOU GIVE OBNLY ONE QUOTE THEN ABAP TREATS IT AS AN ERROR MESSAGE

Try to execute

write : ''''.

we will get a single quote as an output.

Hi Jeyashree,

Generally single quote is used to mark start and end of literal. If you want to display single quote in a string then it is considered as end of the literal and gives you error too. To avoid this ambiguity, we convey the system as double quotes followed by a single a quote is a single quote in a literal.

Thanks,
