NOTES:

When printing a literal string, if the string is greater than 64 characters, the string will break at the first space *after* the 64th and print the remainder of the string on the next line.

SWTPc 4K BASIC seems to want a text file serial transfer with a character delay of 10 ms and a line delay of 300 ms.*, to accomodate long program lines.  The text file should have *carriage return only* line endings.  In general, the shorter the program lines, the more reliable the load.  (*This can be as little as 100 ms. with short, <25 character, lines)
