Using Masm 4.0 at Dos prompt with a legitimate .asm File from a
well-known Author, while linking the Libraries, the error Message...
"Can't find Doscalls.lib" appears. Haven't had this Message before,
although this Author's .asm Files (Directives?) start differently from
the usual layouts with Masm.
Have surfed the Net but can't find a down-loadable File.
Anyone help?
