The semicolon can be used at the beginning of a statement to
prevent zoning of the first item printed. The semicolon can also be
used at the end of a PRINT statement to tell BASIC not to advance
the print pointer to the next line after the print occurs but to leave it
at the end of the line. This is useful when an INPUT statement
immediately follows the PRINT statement.
In Enhanced BASIC, all decimal numbers have 8 digits of
significance. Therefore, only 8 digits can be printed for the number,
whether it is very small or very large. To print very large numbers or
very small numbers, a scientific or exponential format must be used.
For example, the numbers 1.7634736E+17 and 2.8876582E-09
only have 8 digits of precision printed but use scientific notation to
show the number of decimal places to the right or left where the real
decimal point would be placed.
In BASIC, unformatted (using the PRINT statement instead of the
PRINT USING statement) decimal numbers are printed according to
the following rules:
1. BASIC will attempt to locate the decimal point such that there is
no need for an exponent.
Example: 123.45678 or 0.12345678 or 1234567.8
2. If this is not possible, the number will arbitrarily be printed with
one number to the left of a decimal point and an exponent or
scientific notation will be used.
Example: 3.7836524E+12 or 4.8873633E-17
3. If the number is a true fraction and requires no exponent, there
will always be a leading zero in front of the decimal point.
Example: 0.98272635 or 0.18735354 or -0.87725433
PRINT USING allows you to print numeric fields with a specific
number of decimal places and field width:
PRINT USING #logical_device_number,formatted_ print_ list
where:
logical_device_number =
the logical number assigned to a device(PRINT
USING to a channel is not permitted) during an
OPEN statement. If no device number is given,
default device is PORTA on the Processor
module on which the task resides. Most
application task I/O can be handled through
the default port.
