First UMAT example in verification Manual

[nitinchandola]

I have ABAQUS 6.7-1. I was trying to run a user subroutine which did not work. It showed ifort.exe missing. I have installed the Intel Fortran Compiler now.
I tried running the first UMAT example in the verification manual but it showed the following error:

Does the first example work? what does this error message mean? Can I read about this in some section of the Manual?

Those are very strange error messages. The example in the verification manual should work without problems. Are you using the recommend version of the Intel Fortran compiler?

These look like minor syntax errors in the code. Have you spaced the code correctly?
Best to read through the Abaqus Theory Manual for user-subroutines.
The first time I ran my user element, it gave a similar list of minor syntax errors.
