Saved Message Utility
set and the process terminates abnormally. Other debuggers can create a save file but 
refer to the result as a process snapshot file. 
See also process snapshot file.
Saved Message Utility. See SMU functions
shared file. A standard file that your program can open multiple times. Each time your 
program opens the file, it is granted a connection to the same Guardian file open. 
Shared files are managed by the CRE. The CRE supports three shared files: standard 
input, standard output, and standard log. 
shared run-time library (SRL). An object file that the operating system links to a program 
file at run time. See also Transaction Application Language (TAL)
 and TNS/R native 
shared run-time library (TNS/R native SRL)
signal. The method by which an environment notifies a process of an event. Signals are 
used to notify a process when an error that is not related to input or output has 
occurred. 
See also OSS signal, TNS State Library for TNS/E, TNS/E native signal, and 
TNS/R native signal
.
signal handler. A procedure that is executed when a signal is received by a process. 
single-language program.  program in which all routines are written in the same 
programming language.
small memory model. A program attribute that specifies that the program’s heap is 
allocated in the user data segment.
SMU functions. Saved Message Utility (SMU) functions provided by the Common 
Language Utility Library of the CRE. COBOL, FORTRAN, and TAL routines can call 
SMU functions to manipulate saved startup, ASSIGN, and PARAM messages.
SRL. See shared run-time library (SRL)
standard file. A file that your program can use with little or no need to establish file 
parameters. The CRE supports three standard files—standard input, standard output, 
and standard log—that correspond to the files STDIN, STDOUT, and STDERR in a C 
programming environment.
standard input. A file from which a program can read sequential records. Each program 
defines how standard input is used according to the needs of the application. Standard 
input is analogous to the file STDIN in C.
standard log. A file to which a program can write sequential records. The records written to 
standard log are usually informational, warning, or error messages that describe 
exceptional conditions in a program. Standard log is analogous to the file STDERR 
in C.
