use subinstr(), e.g.,

subinstr(var1,",","",.)

and then use real()

I am trying to convert a series of string variables to numeric variables.
Because some of the numbers contain commas, the real() function does not
work, instead returning a missing value.

What I get
String    Number
5.3        5.3
hello           .
>2              .
2,500,000    .

What I want to get
String  Number
5.3             5.3
hello           .
>2              2
2,500,000       2500000

Is there any way to extract a numeric value from the string variable?

Thanks,
Shawn
