Do Loop While
Repeatedly executes the statements between Do and Loop while the specified condition meets.
Format
Do
<statement>
Loop While <expression>
Parameter
Return value
None.
Description
The statement is repeatedly executed if the specified logical expression by the <expression> parameter is
true as a result of the specified Do block execution by the <statement> parameter.
If the Exit Do statement is used in the Do block statement, the statement force stops the repeating execution
of the program immediately.
If the program process is jumped into or out of the Do block statement using the Goto or Gosub function,
unexpected operation may occur.
If neither the Do statement nor the Loop While statement is used, either the "DO without LOOP", "LOOP
without DO", or "EXIT without DO" error will occur depending on the statement that is used.
If the format is written incorrectly, such as writing the macro function name incorrectly, omitting a comma, or
omitting a half-width space, a "Syntax error" error will occur.
Usage Cautions
• None.
Example
Repeats the process until the loop counter reaches a constant value.
