It is often desirable to have general procedures. Ones that
can be used for more than one narrow purpose. We have seen that
this can be done with logical names in the VAX/VMS environment.
A better way in many cases is to pass names to the procedures.
In much the same way you have passed names and arguments to
the text editor and compilers. To do this systems assign special
names to passed arguments in command procedures. In VAX/VMS
the names are P1, P2, and P3 for the first
second and third arguments
passed. In MS-DOS batch files they are %1, %2, and %3.
UNIX systems would use the names $1, $2, and $3.
In this I would like you to write a general purpose
command procedure to compile, link, and run a FORTRAN program.
- Using FORTRAN lab as a guide, create a general purpose command
file for, compiling, linking and running FORTRAN programs. In
a file named DOFOR.COM, put all the commands, with dollar signs
(
$), except whenever you find CIRCLE, replace it with 'P1' (single
quotes included). For example, the first line would be
$ FORTRAN 'P1'
Also add a comment ($!) line at the top with your name and the
date.
- Test it and make sure it works. Set verify on, then
$ @DOFOR CIRCLE
Everywhere you had 'P1' you should see CIRCLE, and it should
compile and execute. Don't forget to set noverify when you're
finished.
- Submit it as a batch job with parameters.
$ SUBMIT DOFOR.COM /PARAMETER=(CIRCLE)
Turn in a copy of the .LOG file marked with:
Your-Name
Lab 4.13: VAX Variables #1 - FORTRAN - DOFOR.COM

Place the lab in the instructor hand-in box
in BUS R6E, the "terminal room".
