CHR or CHR$ crashing running Spectrum

[Luzie]

The library ( <!-- m --><a class="postlink" href="http://www.boriel.com/wiki/en/index.php/ZX_BASIC:Library#Text_Handling_Library">http://www.boriel.com/wiki/en/index.php ... ng_Library</a><!-- m --> ) has putchars ( <!-- m --><a class="postlink" href="http://www.boriel.com/wiki/en/index.php/ZX_BASIC:Putchars.bas">http://www.boriel.com/wiki/en/index.php ... tchars.bas</a><!-- m --> ), which can drop a single character to the screen as well. It doesn't deal with attributes, which would require a separate function ( like, say <!-- m --><a class="postlink" href="http://www.boriel.com/wiki/en/index.php/ZX_BASIC:WindowPaint">http://www.boriel.com/wiki/en/index.php ... indowPaint</a><!-- m --> ) to do that.

Thanks for your suggestions, I´ll have a try with putchars as my next attempts!
