VBA Package

The VBA built-in package collects the standard runtime library --- the modules grouping the standalone procedures (MsgBox, CStr, Mid, Format, …), plus a small number of intrinsic classes (Collection, Err) and twinBASIC's runtime expression engine.

Classes

• Collection -- ordered set of values or object references, accessed by 1-based index or by optional string key
• ErrObject -- the singleton Err object holding information about the most recent run-time error
• TbExpressionService -- runtime expression engine -- parse and evaluate twinBASIC-syntax expressions supplied as strings

Modules

• (Default) -- unqualified low-level intrinsics -- the GetMem / PutMem family, AllocMem, atomic operations, compile-time reflection, codegen and stack-inspection primitives, …
• Compilation -- compile-time intrinsics that record the project, component, procedure, and source file at the call site
• Constants -- global character, pointer, and error-base constants reachable without qualification (vbCrLf, vbNullString, vbObjectError, …)
• Conversion -- type coercion (CBool, CDate, CType, …), number ↔ string parsing, base conversion, and Variant-with-error construction
• DateTime -- reading the system clock, building Date values from components, parsing them out of strings, and shifting them by chosen units
• FileSystem -- pathname-based and file-number-based operations on files and directories
• Financial -- annuity calculations, internal-rate-of-return analysis on variable cash flows, and asset depreciation
• Information -- Is… predicates, VarType / TypeName, array bounds and construction, raw pointers (ObjPtr, StrPtr, VarPtr), and RGB colour helpers
• Interaction -- dialogs (MsgBox, InputBox), inline conditionals (Choose, Switch, IIf), process launching, registry helpers, environment, and dynamic-dispatch primitives
• Math -- sign and magnitude, trigonometry, exponentials and logarithms, the square root, rounding, and pseudo-random numbers
• Strings -- measuring, searching, slicing, padding, joining, splitting, and formatting String values

INFO

The modules listed above are used for grouping documentation, they don't always match exactly with the implementation details of the VBA package.
