code.

=====================
=======  GOTO  =======
KEYWORD: GOTO
DESCRIPTION: Jumps execution to a specific line number.
SYNTAX: [LINE] GOTO [LINE_NUMBER]
EXAMPLE: 10 GOTO 50
=====================
=======  HALT  =======
KEYWORD: HALT
DESCRIPTION: Halts the execution of the program safely.
SYNTAX: [LINE] HALT
EXAMPLE: 99 HALT
=====================
=======  IF  =======
KEYWORD: IF
DESCRIPTION: Conditional branching. Supports the INDEXOF function for
substring searching.
SYNTAX: [LINE] IF [CONDITION] THEN [ACTION]
CONDITION_OPERATORS: ==, !=, >, <, >=, <=
BUILTIN_FUNCTIONS: INDEXOF(str, search) -> returns -1 if not found.
EXAMPLE: 10 IF STATUS == 200 THEN GOTO 50
EXAMPLE: 20 IF INDEXOF(RAW_DATA, "ERROR") > -1 THEN HALT
=====================
=======  JSON  =======
KEYWORD: JSON
DESCRIPTION: Hunts for and extracts a valid JSON block ({...}) from a raw
string (e.g., stochastic LLM output) and parses it into a MAPPING object.
SYNTAX: [LINE] JSON EXTRACT FROM [SOURCE_VAR] INTO [DEST_VAR]
EXAMPLE: 10 JSON EXTRACT FROM RAW_LLM_TEXT INTO PARSED_DATA
EXAMPLE: 20 PRINT PARSED_DATA["status"]
=====================
=======  LET  =======
KEYWORD: LET
DESCRIPTION: Assigns a value to a standard variable. (Functionally
interchangeable with SET for flat variables).
SYNTAX: [LINE] LET [VAR_NAME] = [EXPRESSION]
EXAMPLE: 10 LET PROMPT = "Hello AI"
EXAMPLE: 20 LET SCORE = 5
=====================
=======  LINE_NUMBERS  =======
CONCEPT: FRACTIONAL LINE NUMBERS
DESCRIPTION: x-mesh-basic supports standard floating-point line numbers to
allow infinite zero-collision patch insertion between existing lines.
RULE: Lines are executed in strict ascending mathematical order.
EXAMPLE:
10 PRINT "A"
10.5 PRINT "B"
10.001 PRINT "A.1"
20 PRINT "C"
OUTPUT_ORDER: 10, 10.001, 10.5, 20
=====================
=======  OLLAMA  =======
SYNTAX: [LINE] OLLAMA [PROMPT_EXPR] INTO [VAR_NAME]
DESCRIPTION: Queries local Ollama instance at localhost:11434 using llama3
synchronously.
=====================
=======  PATCH_LOADER  =======
CONCEPT: DROP-IN PATCH DIRECTORY (.d)
DESCRIPTION: When loading /path/script.bas, the interpreter automatically
checks for /path/script.bas.d/.
RULE: Any .bas files in the .d/ directory are loaded in alphabetical order.
Their lines are merged into the main program state before execution begins.
RULE: If a patch contains a line number that already exists, it OVERWRITES the
original line.
EXAMPLE_STRUCTURE:
main.bas
main.bas.d/001-fix-login.bas
main.bas.d/002-add-logging.bas
=====================
=======  PRINT  =======
KEYWORD: PRINT
DESCRIPTION: Evaluates an expression and outputs it to the console.
SYNTAX: [LINE] PRINT [EXPRESSION]
EXAMPLE: 10 PRINT "Hello World"
EXAMPLE: 20 PRINT MY_VAR
=====================
=======  README.TXT  =======
This directory should contain each x-mesh-basic supported keyword and language
structure and idea, IN THEIR SEPARATE FILES, as both documentation and example
usage and spec
