Control File Items

R[n]:e[.f][/b]

n represents the file number and is optional. If not specified, it is assumed to be 6 (six). If specified, the file number must be 3 - 999 decimal.

e specifies the element number (three words per element) within the Control file. It must be 3 - 999 decimal.

f identifies one of the valid Control fields. The valid fields for Control files are listed in the table. If .f is omitted, it is assumed to be the word containing the status bits.

b is optional and is normally not used. Specifying the .f fields can access all of the fields of a Control file. However, it is possible to use /b to single out a bit in the .LEN or .POS fields (which are words). If specified, it indicates the bit (0 - 15 decimal).
