			===Examples===
			The following code uses a DO LOOP combination to allow a [[Check Box]] GUI to work:

			00350 do
			00360 input fields "22,14,CHECK 8,,10;23,14,CHECK 8,,11;24,14,CHECK 8,,12": Box$(1),Box$(2),Box$(3)
			00370 print fields "24,1,N 2": Fkey
			00380 loop While Fkey~=99

			In this case, pressing ESC will set the Fkey equal to 99 and exit the loop.

The '''Loop''' [[statement]] works in conjunction with [[Do]] and [[Exit Do]].

DO/LOOP structure can be used to replace [[GOTO]] statements for more structured programming. Notably, [[labels]] or [[line numbers]] are not required to exit the loop.

The DO and LOOP statements must always be used in conjunction with one another to specify the beginning and ending of the loop. The Exit DO statement may be used to break out of the loop.

===Syntax===

===Default===
1.) When no WHILE or UNTIL condition is specified, continue executing the loop until the DO statement's conditions or an Exit DO indicate otherwise.

The WHILE keyword indicates that execution should return to the previous DO statement only if the specified conditional expression evaluates to true. If the conditional expression evaluates to false, execution will skip to the first line following the LOOP statement.

The UNTIL keyword indicates that execution should return to the previous DO statement only if the specified conditional expression evaluates to false. If the conditional expression evaluates to true, execution will skip to the first line following the LOOP statement.

The LOOP statement must be the last statement in a line, and the LOOP keyword is always required. [[CONFIG]] [[STYLE]] [[INDENT]] will cause lines between the DO and LOOP statements to be indented.

See the [[DO LOOP]] and [[Exit Do]] statements in this section for additional information about the DO/LOOP structure.
