[gradsusr] Tutorial assistance

[Mayes, Fred]

I am attempting to go through the tutorial for the Windows version of GrADS,
http://ieges.org/grads/gadoc/tutorial.html .  I performed the operations

clear
set lon -90
set lat   40
set lev 500
set t 1

on the data set model.ctl. In doing so, I received back after the "set lat 40" command the statement,
"LAT set to 42 42".  Is this to be expected?

After this, I gave the command "d z" and received back an "Invalid Operand" notice that "z not a variable or function name."
Please advise.  Thanks.
