B/MANIF/TSSPREFIX defines the symbolic names for words in the prefix area a program running under TSS. The prefix area occupies the first 100 words of the program and is used for communication with TSS.
Before SR2500, these symbols were defined by the UST manifest file, so programs that need to be compiled on releases earlier than SR2500 may also need to include B/MANIF/UST.
