I used to use it all the time in Perl, where it is the normal behavior of the substr() function, to pull a fixed-width field out of a line of text without having to worry about short lines. If the field was at the end of the line, the result was short; if the field was not present, the result was the empty string. In some contexts, I would then concatenate spaces to it and truncate the result to the desired width. -- Barry thirteen gules and argent on a canton azure John Cowan fifty mullets of five points of the second, [email protected] six, five, six, five, six, five, six, five, and six. --blazoning the U.S. flag http://www.ccil.org/~cowan _______________________________________________ Chicken-hackers mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/chicken-hackers
