How to Use This Series

• Run every example in a sandbox or development system compatible with the feature.
• Compare classic and modern versions before using a pattern in production.
• Complete the exercises without looking at the solution first.
• Prefer readability over compressing business logic into one expression.
• Check your target ABAP release and language version because feature availability differs.

What “New Syntax” Means

ABAP 7.40 introduced important expression-oriented features including inline declaration operators and constructor expressions. Later releases expanded the language further. “New syntax” is therefore a family of improvements rather than one single version. Verify each feature in the ABAP Keyword Documentation available for your target system.
