Hi Bug-APL,
I'm a bit confused. The synopsis states "append text matrices A and B horizontally". The example near the function definition uses slightly different phrasing, and provides an example that does not use exactly "HTML∆xbox":
⍝ append boxes A and B horizontally:
⍝
⍝ AABBB AA BBB
⍝ AABBB ← AA xbox BBB
⍝ AA AA
⍝
When I tried what I thought was the correct usage, I get an error (see below). Can someone demonstrate how to use this function?
)COPY /usr/local/lib/apl/wslib5/HTML.apl
A←3 2 ⍴'A'
B←2 3 ⍴'B'
A HTML∆xbox B
