I'm not sure I completely understand the question but here's a try.

Use double quotes for the format keyword so it won't be confused with the single quotes used for EXECUTE().

While you should be able to use EXECUTE(), it might be better to use SCOPE_VARFETCH() to create a new variable given its string name. The little program below prompts the user to create a variable name, and then assigns the output of READCOL into that named variable.

pro test

;Ask user to supply a variable name
vectorname = ''
read,'Enter Vector name: ',vectorname

; Use READCOL to read into a temporary variable
readcol,'test.dat',temp

;Assign temporary variable to user-supplied variable name
(scope_varfetch(vectorname,/enter)) = temporary(temp)

return
end
