8EFB CHAIN

Submitted by Steve Fewell

Description:

Call routine &BDD7 to get the filename after the CHAIN keyword (and place it in the SWA), and load the named
file (which should be a BASIC program) at the PAGE address and check that the program can be read correctly ('Bad program'
message is displayed if not).
Jump to &8F15 to execute the 'RUN' keyword and begin running the program.

Disassembly for the CHAIN routine
