FOR EACH $line IN FILE("data.txt") PROCESS $line ENDFOR The zxdl script shines in scenarios where reliability and low overhead outweigh the need for a full programming language. Here are the most common real-world applications: 1. Legacy System Integration Many banks and insurance companies run COBOL-based backends. A zxdl script acts as a glue layer, converting flat files into legacy-compatible formats without requiring full recompilation. 2. Automated ETL Pipelines Extract, Transform, Load (ETL) operations become trivial: Check for existing output files before processing

#INCLUDE common/error_handling.zxdl #INCLUDE common/ftp_utils.zxdl Ensure that running the same script twice does not produce duplicate results. Check for existing output files before processing. Log Aggressively The LOG keyword is your best debugging friend. Include timestamps and context variables. Version Control Your Scripts Since zxdl scripts control critical automation, store them in Git (or equivalent). Treat them as source code. Validate External Dependencies Before a script runs, check that all required files, directories, and network resources are accessible:
