/**

• Simple function that tests a full version string against the individual

• platform version constants to determine if the platform's version is at

• least as high as the argument.
  *

• Note that this function will be evaluated at compile-time if the argument

• is a constant. This makes it useful for embedding in #IF() declarations:
  *

• #IF(PlatformVersionCheck('6.2.0-1'))

• OUTPUT('Platform check TRUE');

• #ELSE

• OUTPUT('Platform check FALSE');

• #END
  *

• @param v The minimum platform version in either xx.xx.xx, xx.xx,

• or xx format (where xx is an integer and does not need

• to be zero-padded); extra trailing characters (such as

• the '-1' in the example above) are ignored; REQUIRED
  *

• @return If TRUE, the platform's current version is equal to or higher than

• the argument.
