DRL.CF - read or write the TSS core file.
Usage:
B:
drl.cf( vec, count, index, readflag );
C:
#equate B_drl_cf drl.cf
void B_drl_cf(void *vec, int count, int index,
int readflag);
Where:
- vec
- is the address of the first word in the user program that is
to be transferred to or from.
- count
- is the number of words to transfer.
It should be in the range 1 to 10.
- index
- is the index of the word in the core file to be transferred.
It too should be in the range 1 to 10.
- readflag
- should be 1 if the core file is being read, and 0 if it is being written.
Description:
TSS allocates 10 words in the UST for communication between subsystems.
This space is called the "core file".
DRL.CF provides a convenient way to read/write data from/to this space.
Notes:
The words are numbered from one to ten, NOT zero to nine.
