How to avoid that "3" be in "34" ?

[André.Bisseret]

Hello,

If I have “AB-b3” in myVar and “AB-b34” in a fld “myField”
when I script :
If myVar is not in fld “myField” then put cr & myVar after fld “myField”
AB-b3 is not added to myField !! It is “considered” as being already in 
fld “myField” ; well, I understand why ((AB-b3)4)
But how could I avoid that ?

Thanks in advance for help !
André
