In CP/M'
BASIC-SO, release 5.0, a number of addi-
tions have been made to disk I/O capability:
1.
After a GET statement, INPUTi and LINE INPUTt may be done
to read characters from the random file buffer.
PRINTt,
.PRINTt USING, and WRITEt may also be used to put characters
in the random file buffer before a PUT statement.
In the case of'WRITEt, BASIC-SO pads the buffer with spaces
up to the carriage return.
Any attempt to read or write
past the end of the buffer causes a "Field overflow" error.
2.
/S:
line to set the maximum record size for use with random
files.
The default record size is 128 bytes.
A new feature has been added to the INPUT statement.
A comma
may be used instead of a semicolon after the prompt string to
suppress the question mark.
For example, the statement
INPUT "ENTER BIRTHDATE",B$
will print the prompt with no
question mark.
