The SAP ERP software UI dates back to the 80s, and is still basically all text based, even the tables are still made out of ASCII chars.
Screenshot of an text based table (SAP ERP): https://mysapbasis.files.wordpress.com/2015/02/screenshot1.j... ... the table borders are drawn over the all text (= a lot of space and tab chars) based table.
Textfields cannot be longer than 40 chars, multiline textfields don't exist (basically one textfield per line) and it looks like a dinosaur UI in 2015 - optimized for 14" CRT monitors. Their HTML4 Netweaver UI and Java "experiments" failed.
The ABAP script language dates back to the 80s too and looks like COBOL. https://en.wikipedia.org/wiki/ABAP
