S0 scripting language

Encyclopedia : S : S0 : S0S : S0 scripting language

S0 is an esoteric programming language. It is similar to the scripting language AutoIt. It was designed as an aide to users of Windows to make some tasks (like logins or the monitoring of processes) easier. This design goal was thwarted by poor forethought, making S0 a difficult language in which to code.

Syntax

Syntax comprises of three-character keywords that attempt to be mnemonic. These keywords control program mode, program flow, input, output, memory usage and so on.

Purpose

S0 is a very flexible language, but by far the easiest things to do are simple starting / ending of processes and input / output of text. Mathematics is difficult to impliment in S0, nevertheless, S0 is Turing-Complete.

S0 allows for:

extensive file IO
input and output with IO streams
access to the windows clipboard
access to system date and time
ASCII conversions
a stack
access to processes (start, terminate and push to stack)
Send Keys functionality (sends keystrokes to the active window)
subroutines (infinitely nestable)
a fixed number of flags and counters
Two multi-mode memory registers
scripts to be run within other scripts
the current script to be replaced by fresh instructions read from file in mid execution
Literals file interpretation (a Literals file is a sort of #define file)
a Dynamic Script Element (allows the interpreter to reinterpret the script at runtime to replace flags with values)

Examples

This program prompts the user to enter a number, an operator and another number, before starting the Windows® calculator and sending the sum to be performed as a series of keystrokes. The calculator is left open with the result of the keystrokes displayed.

BEG
IMS 2 // Set input mode to 'console' .
OBS false // Don't output line breaks automatically.
AMS 1 // Append to memory.
LIS Type a number:
AAS 
LIS Type a number:
OMS 3
PSS calc // Start calculator
PAU 1000 // Pause to allow it to be completely initialised.
OMS 3 // Set output mode to 'send keys'
SAY // Output
ENT // 'Press' enter on calculator.
OMS 1 // Set output back to console to avoid outputting stray keys.
