In research articles you sometimes find that researchers used CompuStat Data Item 4 or CompuStat Item 162, etc. This means they’ve used a previous version of CompuStat. In the current version of CompuStat these numbers are no longer used, now you see Current Assets – Total or Cash in the request form.
There is a ‘translation-file’ available: click the link Manuals and Overview in CompuStat and go to ‘Variable Translations – Compann Compqtr and PDE’. There you can open the translation file for CompuStat Annual and CompuStat Quarterly.
