save command


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 --> Fortran

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


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?

No, it causes that all variables in the program unit become static.

RE: save command

So, the placing of the save command has no relationship to the variables being set to static?
Thank you. :)
