12 HOST()
13 Macro SPITBOL: returns ARCHITECTURE:OPERATING_SYSTEM:SNOBOL_VERSION
14 The string contains three parts, separated by colons. The first
15 part describes the physical architecture, the second describes the
16 operating system, and the third describes the language
17 implementation name and version. NOTE! Architecture names come
18 from the uname(3) library call, and may be different for the same
19 hardware when running different operating systems. Examples:
20 amd64:FreeBSD 12.1-RELEASE-p1:CSNOBOL4B 2.2
21 x86_64:Linux 5.4.0-12-generic:CSNOBOL4B 2.2
22 HOST(0)
24 Macro SPITBOL: returns a string containing the command line
25 parameter supplied to the -u option, if any. If no -u option was
26 given, HOST(0) returns the concatenation of all user parameters
27 following the input filename(s).
28 HOST(1, string)
30 Catspaw SPITBOL: passes the string to the system(3) C library
31 function, and returns the subprocess exit status.
32 HOST(2, n)
34 Catspaw SPITBOL: for integer n returns the n'th command line
35 argument (regardless of whether the argument was the command name,
36 an option, a filename or a user parameter) as a string, or failure
37 if n is out of range.
38 HOST(3)
40 Catspaw SPITBOL: returns an integer for use with HOST(2) indicating
41 the first command line argument available as a user parameter.
42 HOST(4, I<string)
44 Catspaw SPITBOL: returns the value of the environment variable
45 named by string.
