Do while loop
DO
Instructions
WHILE (Test)
Syntax:
<DO_WHILE>
Instructions
...
<CONDITION>...</CONDITION>
</DO_WHILE>
The Do While loop comprises a block of instructions and a condition. The code in the in‐
struction block is executed first, then the condition is applied. If the condition is true, the
function executes the code section again. This is continually repeated until the condition is
false.
Example:
<DO_WHILE>
<DATA name = "PLC/qb11"> 15 </DATA>
<CONDITIION> "plc/ib9" == 0 </CONDITION>
</DO_WHILE>
The tag includes an XML script file.
Contrary to the INCLUDE tag, read-in is first only realized when executing the corresponding
operation.
For large projects, the use of the tag reduces the load time of the customer area and/or the
cycle support. Further, the average level of resources is reduced, as not all of the dialogs
are always called during a session.
Syntax:
<DYNAMIC_INCLUDE src="path name"/>
Example:
<SOFTKEY POSITION="3">
<CAPTION>MY_MENU</CAPTION>
<DYNAMIC_INCLUDE src/>
<NAVIGATION>MY_MENU</NAVIGATION>
</SOFTKEY>
Instruction for situations where the condition has not been met (IF, THEN, ELSE)
