PrintW - print a long string, breaking it at the last space or hyphen before col. 79

[TDarcos]

This is a function I think is useful, and I hope I won't find out that one of QB/QB64pe's more than 20,000 keywords, functions and compiler directives, does the same thing. (Yes, I know it's just under 500, but sometimes it feels like it's a lot more.)

I've created a subroutine called PrintW to take a string, breaking it at the last space or hyphen, printing up to that point, then repeating with what is left of the string. In short, it provides a print with wraparound. 

I have tested it with an appropriate passage, the three paragraph Gettysburg Address.

Code: (Select All)

L$ = "Four score and seven years ago our fathers brought forth on this continent, a new nation, conceived in Liberty, and dedicated to the proposition that all men are created equal."

PrintW L$

Print

PrintW "Now we are engaged in a great civil war, testing whether that nation, or any nation so conceived and so dedicated, can long endure. We are met on a great battle-field of that war. We have come to dedicate a portion of that field, as a final resting place for those who here gave their lives that that nation might live. It is altogether fitting and proper that we should do this."

Print

PrintW "But, in a larger sense, we can not dedicate, we can not consecrate, we can not hallow, this ground. The brave men, living and dead, who struggled here, have consecrated it, far above our poor power to add or detract. The world will little note, nor long remember what we say here, but it can never forget what they did here. It is for us the living, rather, to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced. It is rather for us to be here dedicated to the great task remaining before us, that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion, that we here highly resolve that these dead shall not have died in vain, that this nation, under God, shall have a new birth of freedom, and that government of the people, by the people, for the people, shall not perish from the earth."
