since you are calling out the entire array: r (:, :). Steve Lionel has a discussion of why trying to make arrays obvious with ":" isn't a good idea -- there are differences betweenarrayandarray

is it possible to assign the size and values of a common array in a subroutine and then use it from other subroutines of the program? The following program doesn't work, but I want to do something like this: main.f program main integer n integer, allocatable :: co(:) common n, co ...
The RESHAPE function allows us to assign values to a two or higher rank array when used in conjunction with an array constructor.We have introduced the concept of a deferred-shape array. Arrays do not need to have their shape specified at compile time, only their rank. Their actual shape ...
Cray pointers can be assigned values as follows: Set to an absolute address Example: q = 0 Assigned to or from integer variables, plus or minus expressions Example: p = q + 100 Cray pointers are not integers. You cannot assign them to a real variable. The LOC function (nonstandard) ...

severe (18): Too many values for NAMELIST variable FOR$IOS_TOOMANVAL. An attempt was made to assign too many values to a variable during a namelist READ statement. 19 severe (19): Invalid reference to variable in NAMELIST input FOR$IOS_INVREFVAR. One of the following conditions occurred:...
My question is: what happens if the Python or Matlab user had failed to assign values to the arguments? What then would the Fortran routine find in these arguments when called? NaNs, huge/tiny numbers, garbage? And how can I detect that (without the routine failing)...
