Howdy!

I don't know...

However, the question brings to mind the TUTOR language (used on PLATO many years ago and once again available). The language uses commands with arguments. The commands are flush left, up to seven characters long, then tab to column 8 for the arguments. In the course of its life, structured programming features were added -- if, loop, etc. 

unit    foo
next    bar
if      a > 123
.       at      1010
.       write   a is big...
endif
calc    c <= 0
loop
.       calc    c <= c + 1
outloop c > 10
reloop  c < 5
.       at 1210
.       write   c between 5 and 10
endloop

You could, of course, nest those structures. That made it ugly if you got deep into indentation...especially given that the screen is 32x64. Yeah, uniform indentation is not necessarily a Bad Thing, especially if the alternative is doing without block-like stuff.

PLATO ran on CDC mainframes such as the Cyber. Some folks are running a Cyber emulator on a high-end Pentium box (with a Mac as the backup) on top of which they are running NOS and PLATO. You can read more about it at http://www.cyber1.org.
