IAS Indirect Command Processor Manual

This manual, dated May 1990, describes the IAS Indirect Command Processor (Indirect). It covers the use of indirect command files, which allow users to automate sequences of MCR commands. Key topics include:

• Indirect Command Processing: How to create and execute command files.
• Directives and Symbols: Detailed documentation of directives used for programming (looping, branching, conditional logic) and symbol manipulation (logical, numeric, string).
• Operational Modes: Explanation of features like substitution mode, data mode, and quiet mode.
• Reference Section: A comprehensive reference for all Indirect directives (e.g., .ASK, .IF, .GOTO, .SETN), including syntax and examples.
• Error Handling: Guidance on trapping errors using .ONERR and .ONFAIL.

The manual is intended to help users automate system tasks to improve efficiency and reduce manual typing errors.
