Hi,

When you use the assignment operator with quotes, what ever value is entered within quotes will be assigned to that variable.

Eg,.

data: number type i.

number = '999'.
write: number.

Here 999 will be the output. i,e the value 999 is assigned to number when specified within quotes.

When you use direct assignment,

data: number type i,
         999 type i.

999 = ' 555'.

number = 999.

write: number.

When you assign a variable to another variable you wont use quotes. In the above example 999 is a variable and not a value. Only 555 is the value assigned in quotes. So the output will be 555.

Hope you are clear now.

above post explain clearly .

quotes are useed for char and sting . but when u will assigned to the variable which is a typr of integer then inside quotes values it will assigned to the variable .

but in case of string its must u have to provide a value in quotes. ''

'999' will be considered as hardcode.
