I think I created a verb to create box characters.
I discovered that jhtextarea and jhtml expect different new lines.
I also discovered that only Courier New compared to Courier and Monaco
fonts connects the vertical bars.
Thanks, Eric and Bob.
z =: 9484 9516 9488 9500 9532 9508 9492 9524 9496 9474 9472 - 9344
char =: a.& i.
expand =: (16+i. 11)&( {&1 1j2@(11&>@i.))
mask =: (16+i. 11)&(11&>@i.)
NB. htmlboxchar defaults to apply to an html textarea using LF
NB. <br/> works better with jhtml.
htmlboxchar =: 3 : 0
LF htmlboxchar y
:
Char =. char ,y,"1 x
Starts =. (expand I.@#mask) Char
Expanded =. z([{~16-~mask@] #])`(2+Starts"_)`(expand@] #])} Char
Expanded =. 226 Starts}Expanded
a.{~Expanded =. 148 (Starts+1)}Expanded
