In simplest terms, a single equal sign asks if the values are equal, whereas
a double equal sign asks if the bytes are exactly the same. Thus,

    "A" = " A "   is true
    "A" == " A "  is false

     2 = 2.0      is true
     2 == 2.0     is false

     25 = 2.5E+1  is true
     25 == 2.5E+1 is false

All character comparisons are case-sensitive. To make a case-insensitive
comparison use the TRANSLATE() built-in function. For example,

   IF TRANSLATE(string_1) = TRANSLATE(string_2) THEN ...

performs a case-insensitive comparison of the variables string_1 and
string_2.

Regards

Dave
