Hi

I am new to Fortran (but not programming) and understand that the save command causes the variables of a subroutine to become static prior to an end or return statement but I have this in the code I have received:

Code:
      include 'parm.h'
      include 'xvar.h'
      data ifirst/0/
      data zMmin/9.945d31/

      save

This is the first 5 lines of the code, so there is no return or end statement at this point (there are loads of lines to run after this; the bulk of the work!).

I'm assuming that this save simply causes the first 2 variables (ifirst and zMmin) to become static, but not subsequent variables?
 
 
So, the placing of the save command has no relationship to the variables being set to static?
Wow!
Thank you. :)
