Editing Stratus VOS (section)

===Command Macro Language===
VOS has a fairly complete command macro language which can be used to create menu systems, automate tasks etc. VOS command macros accept arguments on the command-line or via a user interface "form". Arguments are defined at the beginning of the command macro in a "parameters" section. The language supports a range of statements, including if/then/else, Boolean operations, "while" loops, "goto" and excellent error reporting. The command macro language can be executed in interactive and non-interactive (batch or started process) modes. It can be used to automate programs, capturing prompts and sending appropriate responses. This has led Stratus to limit the capabilities of the command macro language.<ref name="Paging discussion">{{cite web|url=http://groups.google.ie/group/comp.sys.stratus/browse_thread/thread/521e96daaf84d858?hl=en |title=Google Groups |publisher=Groups.google.ie |date= |accessdate=2016-05-16}}</ref>

The macro language lacks support for user-defined functions and does not easily support include files.{{Citation needed|date=January 2016}} The string handling is prone to errors, especially with embedded control characters.{{Citation needed|date=January 2016}}
