st: Re: reshape when the stub is at the beginning of the variables

["Michael Blasnik" <michael.blasnik@verizon.net>]

Check out the advanced syntax for reshape.  I believe that you can specify 
the location of the "j" part of the variable names using the @ symbol.  I 
haven't used this option in a while, but I think you will need to specify 
that the j variable is a string and may need to use the atwl() option for 
the reshape xij line.

reshape xij @SMOK
