NAME¶
snobol4host - SNOBOL4 host O/S functions
DESCRIPTION¶
- HOST()
- Macro SPITBOL: returns ARCHITECTURE:OPERATING_SYSTEM:SNOBOL_VERSION The
string contains three parts, separated by colons. The first part describes
the physical architecture, the second describes the operating system, and
the third describes the language implementation name and version. NOTE!
Architecture names come from the uname(3) library call, and may be
different for the same hardware when running different operating systems.
Examples:
amd64:FreeBSD 12.1-RELEASE-p1:CSNOBOL4B
2.2
x86_64:Linux 5.4.0-12-generic:CSNOBOL4B
2.2
- HOST(0)
- Macro SPITBOL: returns a string containing the command line parameter
supplied to the -u option, if any. If no -u option was
given, HOST(0) returns the concatenation of all user parameters
following the input filename(s).
- HOST(1,
string)
- Catspaw SPITBOL: passes the string to the system(3) C library
function, and returns the subprocess exit status.
- HOST(2,
n)
- Catspaw SPITBOL: for integer n returns the n'th command line
argument (regardless of whether the argument was the command name, an
option, a filename or a user parameter) as a string, or failure if
n is out of range.
- HOST(3)
- Catspaw SPITBOL: returns an integer for use with HOST(2) indicating
the first command line argument available as a user parameter.
- HOST(4,
I<string)
- Catspaw SPITBOL: returns the value of the environment variable named by
string.
