Chained statements.

If consecutive statements have identical part at the beginning, then you can chain these statements into a single statement.

First write the identical part once and then place a colon (:). Then write the remaining parts of the individual statements separated by commas.

Example – Normal Statements:-

WRITE ‘Hello’.

WRITE ‘ABAP’.

The Above statement can be written in Chained Statement as,

WRITE: ‘Hello’, ‘ABAP’.

If you want to print the texts in new line, then you can place(/).

WRITE: ‘Hello’,/, ‘ABAP’.

The above statement will print ‘Hello’ in one line and ‘ABAP’ in another line.
