Format Strings
Format Numbers and Align Strings for Display or Table Output
Intention
These Commands provide tools to format numeric values and align strings for clean, consistent output — essential for reports, tables, logs, and user interfaces.
Use `FMT.` to control decimal places or apply custom patterns to numbers. Use `VSL.`, `VSM.`, and `VSR.` to left-align, center, or right-align strings within a fixed width, optionally padding with a custom character.
Command Overview
•FMT. - Format Numeric Output – Format numbers by digit count or pattern
•VSL. - Variable Set Left – Left-align string in fixed width, pad with space or custom char
•VSM. - Variable Set Middle – Center-align string in fixed width, pad with space or custom char
•VSR. - Variable Set Right – Right-align string in fixed width, pad with space or custom char
Key Features
•Flexible numeric formatting: Use digit count (e.g., `|3`) or custom patterns (e.g., `|00.000`)
•String alignment: Left, center, or right align with optional fill character
•In-place modification: All Commands modify the variable directly — no result pushed to TOS
•Binary-safe: Preserves null bytes and special characters
•Default padding: If no fill character specified, uses space (`$sp$`)
