32.83. $cvbo

$cvbo scans s for the STRING representation "TRUE" or "FALSE". Case is ignored. As soon as one of these STRING representations is found or there are no more characters in the source STRING, the scan stops. $cvbo returns TRUE if the characters TRUE were found in the source STRING; otherwise, it returns FALSE.

The character sequences TRUE or FALSE need not be preceded or followed by a blank, tab, or end of line.
