Extending product function with VBA : Programming System Architect with Microsoft VBA
  
Programming System Architect with Microsoft VBA
System Architect stores the current status of its Microsoft VBA project environment in the initialization file SA2001.ini. The section entitled Macros may contain the following:
[Macros]
PermanentAutoLoad1=SAAuto.mac
TemporaryAutoLoad1= c:\program files\UNICOM Systems\system architect suite\system architect\Sample.mac|vxRead|vxShared|vxTransacted|bProjectActive
RunTemporaryAutoMacros=T
OpenReadOnly=T
The above excerpt indicates that the permanent SAAuto.mac project file is loaded when System Architect starts. (It will be hidden and read-only.) The temporary Sample.mac project file is currently active and is also loaded in read-only mode. If any of the temporary project files contain an AutoExec module, then the macros are automatically executed. The default for opening new projects will be Read Only.
