Syntax
... [LEFT|RIGHT] [CIRCULAR] ...
Extras
1. ... LEFT|RIGHT
2. ... CIRCULAR
Addition 1
... LEFT|RIGHT
Effect
The shift direction is defined using LEFT or RIGHT.
If neither of the additions is specified, LEFT is used implicitly. If the
data object dobj is a string and the addition CIRCULAR
is not specified, it is truncated when shifted to the left by the places shifted and lengthened accordingly when shifted to the right.
Example
The content of text field text is moved one place to the right, by which the digit "9" is lost. The data type string would lengthen the string by one space.
DATA(text) = '0123456789'.
SHIFT text RIGHT.
cl_demo_output=>display( text ).
Addition 2
... CIRCULAR
Effect
Using the addition CIRCULAR, the content shifted from the data object to
the left or to the right, is inserted again in the places that become available on the opposite side.
If the addition CIRCULAR is specified, data objects of the type string
or xstring are not shortened or lengthened; instead, they are handled as data objects of fixed length.
Example
This example is a variant of the second example under
places. Using the addition CIRCULAR, the result becomes "you know I know".
DATA text TYPE string VALUE `I know you know `.
SHIFT text UP TO 'you' LEFT CIRCULAR.
