exit repeat

Type​

control structure

Summary​

Skips the rest of the current repeat loop and goes to the statement following the end repeat.

Syntax​

exit repeat

Description​

Use the exit repeat control structure to skip the rest of a repeat loop.

Form: The exit repeat statement appears on a line by itself, anywhere inside a repeat control structure.

After an exit repeat statement, none of the remaining statements in the current loop is executed, and any more loops are skipped. The handler resumes executing at the first statement after the end of the repeat loop.

Usually, exit repeat is used within an if control structure, so that the loop stops if a condition is true and continues if the condition is false. This example reads a file in chunks and stops the loop when it encounters the end of file or if the file is empty:

    constant kChunk = 1024
    open file tFile for binary read
    repeat
        read from file tFile for kChunk
        put the result into tResult
        if tResult is empty or tResult is \"eof\" then
            ProcessFileChunk it
        end if
        if tResult is not empty then
            exit repeat
        end if
    end repeat
    close file tFile
