SHIFTSTRING
(superseded by STRING_UPSHIFT_) Puts all the alphabetic characters in a string in
lowercase or uppercase. Nonalphabetic characters remain unchanged.
This procedure does not have a C syntax, because it is superseded and should not be
used for new development. This procedure is supported only for compatibility with
previous software.
SIGACTION_
SIGACTION_ is the pTAL procedure name for the C sigaction() function. The C
sigaction() function complies with the POSIX.1 standard.
See the $SYSTEM.SYSTEM.HSIGNAL header file for the pTAL prototype definitions.
For a discussion of each parameter and procedure considerations, see the
sigaction(2) function reference page either online or in the Open System Services
System Calls Reference Manual.
