Welcome to our forums
I am just returning to FORTRAN after 40 years so the question may be silly. I set up a logical test
If (a<=c) then (do something) end if.
It does not compile properly but
If (a .le. c) then (do something) end if
Compiles with no problem. Have I just been away too long? Help!
Which compiler did you use, and what options did you specify? What do you mean by 'did not compile properly'?
I tried this program with FTN95 7.2, and it worked fine:
program xle
implicit none
real a,b,c
a=5.0
c=7.0
if(a<=c)then
b=a-c
write(*,*)b
endif
end
Sorry for the long delay. Thank you for the quick response mecej4. It was pure brain fade on my part. Clearly If (a = 1) then is an incorrect logical and should be If (a == 1) then ... It is surprising me how slowly FORTRAN is coming back to me but I will get there. I turn 80 next year and am planning on using it for the next 20 years.
