Re: st: Re: Encode string in batch way?

["Michael Blasnik" <michael.blasnik@verizon.net>]

Here's a couple of ways to check if a variable is numeric:

cap confirm numeric var myvar
if rc==0 {
...
}

or

local vtype: type myvar
if substr("`vtype'",1,3)!="str" {
...
}

It's this latter one that employs the extended macro function : type varname 
that actually allows you to examine the storage type for a variable.
