Hi

I can't find any reference to this - so thought I'd ask.

var1 = "ABCDEF"
If var1 == "ABCDEF" then .....

the above is for an exact match

But instead of '==' [equals], is there a [contains]??

eg:

If var1 [contains] "DEF" then .....

both these 'If's would then be true.

I was hoping that there was a simple replacement for the '=='.

Or even if there is a 'wildcard' or 'ignore' character??

Thank you for any help

You didn't say how you assign your value to "var1", but you could try something like below to isolate the characters before testing the condition:
PHP Code
   string   var1     = "abcdef";
   string   contain  = StringSubstr(var1,3,3);
   if(contain == "def"){
      //then do something
   }
Hope it helps...

Use StringFind()

i.e. StringFind(var1,"DEF") will return 3, because DEF starts in the 4th character position (the first position is 0, the second position is 1, etc).

If the string can't be found, then function returns -1

Hence you could type
if (StringFind(var1,"DEF") >= 0)

which is effectively saying
"if the string DEF is found anywhere in var1"
or, if you prefer
"if var1 contains the string DEF"
