If ...... then ...... Isn't this computer programming language?

I have a question about the "If ...... then ......" structure.  When I first learnt "if", I was told that the structure should be

If you do this, you will ......

But over the years, I noticed more and more people saying

If you do this, then you will ......

I am wondering if this is an influence by computer programming languages or was it always like that before the days of the computer?

Hi, I think few programming languages have the 'if ... then' statement. The origin might be before such industries, IMO.  LiJ

Hi LiJ,

"if ... then" statement may not be common in the more recent programming languages, but they were everywhere in the earlier generation: BASIC, COBOL, FORTRAN, etc.  Microsoft Visual Basic still uses "if ... then".

Hi Pter

I bet you know about IT  far more than I do. The only one I know how to do among languages you mentioned, using 'if then' statemets, is the macro for MS Office.

Thanks for your post.
