The SHELL variable will always have the pathname of your login shell if it 
remains set, regardless of the current shell you're running.  If the SHELL 
variable is set, calling /bin/ksh will not change the value.  If the SHELL 
variable is unset,  #!/bin/ksh will set the SHELL variable to /bin/sh.  And 
actually, if you use #!/bin/sh, the SHELL variable will be set to /bin/bash, 
the Bourne Again SHell. Go figure.

To unset the SHELL variable, type:

unset SHELL

at a command prompt.  After that, your script as it's written will probably 
echo /bin/bash.

As alread mentioned by Mike Ault, remove the spaces on both sides of the = 
sign.
