In addition to Eric's good advice, if the blanks really are just common or garden spaces " ", then 

. replace myvar = subinstr(myvar, " ", "", .)

is the way to go, similarly to his bottom line.

If by 'blanks' you mean 'spaces' then first take a look at -help trim-.  Sometimes blanks or spaces are other, invisible characters.  To find those I use a combination of -charlist-, -ascii- (or -asciiplot-) all user-written programs from SSC.  After installing these programs you can check for these characters with something like:

replace myvar = trim(myvar)
charlist myvar
di "`r(ascii)'"
ascii      //compare the char list with what should be there
**let's say, you found that your string included invisible char 20, then:
replace myvar = subinstr(myvar, "`=char(20)'" , "" , . )
