To revert to behaviour exhibited by AutoCAD 2020 and earlier, you can set the new LISPSYS system variable to 0: LISPSYS (System Variable)Ĭontrols the default AutoLISP development environment and the editor This is caused by the new AutoLISP Unicode character support introduced in AutoCAD 2021, alongside the introduction of VS Code as the primary AutoLISP Editor. I'm lost as to why there is any difference in the new version? Many thanks for your help. It looks like the function errors or returns on the first line break it receives and exits, although in the debugger I can see the regex pairs being processed. However when we process this function with the same input in Autodesk 2021 the output (for str) is: Ranford Rd, Perth WA, Australia The output (for str) in the function should be: AA P100 312F - SMOF FNPEHJC/STDCNVL F CNVL 4701:CNVL AD-CNVL AE/1-312 The input string from the paste is: Ranford Rd, Perth WA, Australia (prompt (strcat ' Error: ' (vl-catch-all-error-message str))) (setq str (vlax-invoke rgx 'replace str (car pair))) (vlax-put-property rgx 'pattern (cdr pair)) (vlax-put-property rgx 'ignorecase acfalse)

(vlax-put-property rgx 'multiline actrue) Modified Lee mac's unformat function - removes formatting from a string The script is below: GDD parser to remove unnecessary info from the paste to prepare for processing We are getting different results using Autodesk 2021 from a script migrated from 2019 and I can't figure out why there is a difference. We have a function, called via the input paste reactor to process some text in a drawing.
