BASIC random access file (BRD).
In other words, cross opens BRD file "DATA RI" on the
floppy disk in drive number 3 to logical number 5, or, if
the file does not yet exist, cross opens so that the BRD
file "DATA RI" can be newly made on that floppy disk.
PRINT #5(11). R(11)
Writes in the content of a one-dimensional numerical
array variable R(l1) to element 11 of the BRD file
opened in logical number 5 by the XOPEN # statement.
PRINT #5(20). AR$.
Writes in string variables AR$ and AS$ to, respectively,
AS$
elements 20 and 21 of the same BRD as above. Because
all elements in the BRD are a fixed length of 32 bytes,
any part of the string length which exceeds 32 bytes will
be invalid.
INPUT #5(21). R$
Reads out (substitutes), to string variable R$, the data in
element 21 of the BRD file opened to logical number 5 by
the XOPEN # statement.
INPUT #5(11). A(11). Reads out the data in elements 11 and 12 of the BRD, as
A$(12)
described above, to the one-dimensional numerical array
variable A(11) and one-dimensional string array variable
A$(12) respectively.
CLOSE #5
CLOSE
Closes the BRD file opened to logical number 5 by the
XOPEN # statement.
Closes all files opened by WOPEN, ROPEN or XOPEN.
