expr

Any expression.

Use asString if you want to be sure that a value is string. If a variable was not declared with Dim then it can contain value of any type and can behave in different way in expressions.

str1 = 123.456
|
str2 = 123
|
print str1 + str2 ' result is 246.456
|
print asString(str1) + asString(str2) ' result is "123.456123"
