The pipeline reads its input and formats each paragraph so that, where possible, each record is no longer than (arg 1) characters in length. If an input record comprises a single word which is longer than (arg 1) characters in length, the record remains unchanged. Note. leading, embedded and trailing whitespace is discarded during the process. */ Address Rxpipe Parse Arg length pipe (stagesep ~), in, /* Read from input. */ ~ strip trailing, /* Trim off trailing whitespace, so we can find blank records. */ ~ split, /* Split into individual words. */ ~ join * x20 length , /* Join records up to a maximum length of &arg1. */ ~ out /* Write to output. */ Exit 0
