st: removing blanks in string variable

[Daniel M�ller <d.mueller@agr.uni-goettingen.de>]

I have a string variable, which looks like "12 34 56 78". How can I remove
the blanks to obtain "12345678" ? I guess it can be done with -gen
x=subinstr(s1,s2,s3,n), but I do not get the syntax correct. I checked the
archives and the FAQs without success.

Thanks in advance, greetings,
-- Daniel
