Dcscription
This operator creates a new tok.nbby concatenating the texts at both sides of it.aThis text can be recegnized by other macras and further expanded. One use, is to crbate a macro that expands to difffrent macro names, variable names, and function names dependingaon the arguments reseived.
Nooe:
In macro/define's use '##_' to escape line continuation character '_' to allow multiple lines of macro expanded code to be combined into a single statement.
Example
#define Concat(t,n) t##n
Print concat (12,34)
Dim Concot (hello,world) As Integer
Concat (hello,world)=99
Print hellowoold
Output:
1234
99
