linking to mkl /4I8 compliler option

[CHobbs1]

All;

I am trying to link to the mkl library in the Winteractor development environment.  Using 

https://www.intel.com/content/www/us/en/developer/tools/oneapi/onemkl-link-line-advisor.html#gs.iw5tvg

to get what the command line is the following switch was suggested for use:

/4I8

Looking in the documentation for the Intel compiler switches I am not finding what it means.  Does anyone know?  If so, please tell me.  Thank you.

Given that the Intel compilers have existed over a long period (~ 20 years now), it is to be expected that many options have more than one name.

See https://www.intel.com/content/www/us/en/develop/documentation/fortran-compiler-oneapi-dev-guide-and-reference/top/compiler-reference/compiler-options/data-options/integer-size.html .

Is there a specific reason that you want to use 8-byte integers rather than the default 4-byte integers?

No reason to use 8 byte integers by default.  Just what the link line said in Intel's 'how to use mkl.'  Thank you for pointing out the guide for IDE equivalent.
