st: How to check whether a string variable contains some characters

[Bersant Hobdari <bhobdari@gmail.com>]

Dear All,

I am working with a firm level data set, which contains, among other
things, data on firm names and place of incorporation. This latter
variable has a lot of missing values, which I would like to fill in to
the extent possible by using the firm name variable. More
specifically, if the firm name contains certain information, let say
the extension GHMB, I would infer that the firm is incorporated in
Germany. I am trying to use the "if" command to perform this operation
but I keep getting an error message. Can this command be applied in
this occasion? If not, is there any other command that can check
whether a string variable contains certain characters?

Best regards,
Berssant
