Re: [ferret_users] concatenating strings with integers

["Paulo B. Oliveira" <pboliveira@xxxxxxx>]

Hi Marco,

I frequently create this type of strings inside a loop:

let First = xsequence({ "one", "two", "three" })
let Second= xsequence({ 1, 2, 3 })

repeat/i=1:`First,ret=iend` ( let Third = "`First`_`Second,zf=2`" )

I don't now how do it outside the loop, but using your idea you can reach the result using:

let tmp = floatstr(second,"(f0.0)")
let tmpl = strlen(tmp)-1
let third = substring(tmp,1,tmpl)

... not neat, but works...
