To make sure things get written on one line you should either
concatenate the strings ('+') or use a format specifier.

print,a[[0]]+'>' gives you what you want as does
print,a[[0]],'>',format='(2A)' or print,a[[0]],format='(A,">")'. On
the other hand, even print,a[0],'>' will break the line if a is too
long. Example: a=string(bytarr(100)+64B) & print,a[0],'>' (whether
the number is 100 or something greater depends on your display window
width).

Cheers,
Martin
