SORTMERGESTATISTICS
Use the pTAL compiler syntax checking option to detect if a pTAL program requires
any changes. C and C++ programs do not require changes. See the procedure’s
description in the Guardian Procedure Calls Reference Manual for more details.
Writing Multithreaded Programs
Native processes do not maintain the TNS register and stack architecture. Thus, user-
written multithreaded programs that directly manipulate TNS registers and the stack
require changes to be converted to native mode. Programs must use a new set of
multithreaded support procedures. The multithreaded support procedures enable
programs to save and restore thread context and to create the context for new threads.
Both TNS and native programs can use the multithread support procedures. See
Support Note S96001, “T9050: User-Level TNS/R Native Thread Primitives” for details.
