Let me add one comment to Joseph's characteristically
lucid and detailed explanation.
- -string()- and -tostring- are really the same idea
at
two different levels.
The -string()- function is more fundamental, and does
the hard work of converting numbers to strings.
The -tostring- command is, from one point of view,
a wrapper for -string()-, as may be seen by glancing
at the code:
. viewsource tostring.ado
The difference -tostring- makes is twofold:
convenience
and protection. You can process several variables at
one and there are some safeguards inhibiting you from
doing some dopey things.
