The reason is that because of the halt() statement, the temporary 
ansistrings that have been generated can't be released. It's strange 
that a temporary ansistring is generated though. It's for the 
"StrPCopy(szDevNbr,sDevName);" statement. sDevName is a normal 
shortstring, but the compiler insists on first converting it to an 
ansistring and then uses the strpcopy(pchar,ansistring) routine (instead 
of just calling strpcopy(pchar,shortstring). Strange.
