As promised, here are the results of 9 different methods of appending.
Basically program went like this:
A=""
FOR I=1 TO 50000
A<1,-1>=I
NEXT I
Style 1: <1,-1>
straight.......................................................1 minute, 29
seconds
Style 2: <-1> attribute level then CONVERT to
253...............................41 seconds
Style 3: DIM(50,000), MATWRITE, READ & CONVERT.............................2
seconds
Style 4: DIM(50,000), then assign to variable and CONVERT to 253............1
second
Style 5: Target = null, []
replacing........................................................40 seconds
Style 6: Target=Space(1000000), [] replacing then TRIM........8 minutes, 55
seconds.
Style 7: Append, VM assigned inside
loop..............................................41 seconds
Style 8: Append, VM assigned outside loop then remove last..................34
seconds.
Style 9: <1,MV> with MV+=MV as pointer.............................1 minute,
28 seconds
60 user D3 system on W2000 during normal business day.
It appears that Styles 3 & 4 escaped the suggestions and rose to the top.
Apparently the CONVERT (or RAISE/LOWER) functions are pretty quick. The DIM is
incredibly quick.
I learned a lot and hope others can as well.
Thanks for everyone's suggestions.

If anyone wants further coding for any of the styles then don't hestitate to
ask.
