eq compares tokens.

"1 ~ eq 2" means: "1" "~" == "2". Two tokens "1" and "~" compares to one token "2"

"~ 1 eq 2" means: not "1" == "2". Not one token "1" compares to one token "2"

not work.

Code:

ee1 = 'do '
         ee2 = 'some'
         if ee1 ee2 eq 'do some'
         display 'yes!' ;I not get yes!
         end if

define ee1 'do '
         define ee2 'some'
         if ee1 ee2 eq 'do some' ;I not get yes!
         display 'yes!'
         end if

 if ee1  eq 'do ' ;I  get yes!
         display 'yes!'
         end if

if ee1  eq 'do ' & ee2 eq 'some'
         display 'yes!' ;I get yes!
         end if 

if ee1 ~ eq 'do ~'
         display 'yes!' ;I not get yes!
         end if  
if ee1 ~ eq '~'
         display 'yes!' ;I not get yes!
         end if

Appears to be working fine.

What makes you think it isn't working?

Note that it doesn't compare strings, it compares tokens.

Its work.

Code:

define ee1 'do '
define ee2 'some'

if ee1 ee2 eq 'do ' 'some'
         display 'yes!' ;I get yes!
         end if   

tokens equ 'do ' 'some'
if ee1 ee2 eq tokens
         display 'yes!' ;I get yes!
         end if
