Deck & include commands in Fortran

Deck & include commands in Fortran

Deck & include commands in Fortran

Hi, I want to understand a subroutine which is written in Fortran.
Program contains the following commands


What are these commands do? Where can I find information about them?


RE: Deck & include commands in Fortran

Thanks, I have found the answer!
*deck is only a comment! I have forgotten that in f77, * indicates comment line too!

RE: Deck & include commands in Fortran

"* indicates comment line too!"

not in any dialect of fortran that I have ever seen in the past 30+ years !

RE: Deck & include commands in Fortran

I mean , C or * at the first column indicates a comment line. I have still problem with #include  command! what is this command?

RE: Deck & include commands in Fortran

this is the subroutine:

*deck,usermat  parallel           user                             gal
      subroutine usermat(
     &                   matId, elemId,kDomIntPt, kLayer, kSectPt,

     &                   nDirect,nShear,ncomp,nStatev,nProp,
     &                   Time,dTime,Temp,dTemp,
     &                   stress,ustatev,dsdePl,sedEl,sedPl,epseq,
     &                   Strain,dStrain, epsPl, prop, coords,
     &                   rotateM, defGrad_t, defGrad,
     &                   tsstif, epsZZ,

#include "impcom.inc"

An asterisk is not a valid character to start a comment line.

#include "impcom.inc"   would mean that the contents of a file called "impcom.inc" are to be inserted into the source code at this position.

Thank you very much for your reply. Could you give me please a reference for more information?
