integer N,l,Tsteps

logical PBC

print*,"Input Number"

read (*,*) N

print*,"Number=", N

print*,"Input Square Grid Size (one number; LXL)"

read (*,*) l

print*,"Grid length and width is ", l !Want this to say l x l; is there a way to do it? Again, I'm new at this.

print*,"Input time"

read (*,*) T

print*,"Time =", T

print *, "True or False?"

read (*,*) PBC ! How do I get this so that it recognize .true. or .false. from this statement?

Integer,parameter :: n=N ! Will this work?

integer, parameter :: L = l

integer, parameter :: t=T

logical, parameter :: pbc = .PBC.

So in summar the 3 questions are:

1) how do i output something to say " * and * "

2) How do I get a user input statement to be recognized into a logical term?

3) how do I get integers to transform into parameters (or can I just have the input already be in parameter form?)

Thank you for your help
