EZscript Script Editor
EZscript Scripting Language
The EZscript is an Actian DataConnect scripting language that includes functions, operators, statements, variables, object variables, and error objects. EZscript is similar to Visual Basic (VB), but there are a few key differences such as:
• EZscript supports both functions and subroutines (a user-defined function may or may not return a value). The scripting language does not distinguish between them in the definition.
• EZscript is supported in both Windows and Linux platforms.
• EZscript does not include all VB script functions. However, EZscript includes custom functions that are nonexistent in VB such as the file management functions FileRead and FileRename.
EZScript Editor
The EZScript Editor is the interface for creating and managing EZscript expressions. You can use the EZScript Editor to:
• Create or modify EZscript Library artifacts in Project Explorer and then use them in a map.
• Define filters for source and target fields
• Define sort options for source data
• Add an expression for the applicable target fields in the map.
• Specify a value for the applicable parameters using EZscript when adding events to a map
• Add EZscript step or add expressions in Start or Stop step in process to specify input/output file, define properties of message components, or mange logical variables.
