What Is Not Included in This Manual?
This manual is intended for experienced system programmers and so does not explain
TAL programming or the operating system. Also, this manual does not describe the
syntax of GDSX supported pseudo procedures that function exactly like their
corresponding Guardian, NonStop TS/MP, Pathway/TS, and NonStop TM/MP
procedures because those procedures are explained in other manuals.
Finally, this manual was not written as a cookbook that may be followed step by step to
develop a given application. Although essential information, tutorials with working
examples, and guidelines are provided for development of typical applications, not all
applications could be anticipated for this very adaptable product.
