This situation arises because of the format in which information
is stored on disk files. When a PRINT statement is directed to the
display, if commas are used to delimit parameters, each
parameter is displayed at the next tab position on the screen.
However, when PRINT statement output is sent to a disk file, the
commas are ignored. Therefore, all parameters are concatenated
until the carriage return character (ASCII 13) is encountered. In
DOS, the carriage return character is the only character which
can be .used to separate values.
In
Integer BASIC, a carriage return character is output after the
fifth tab stop. In Applesoft BASIC, a carriage return character is
output after the third tab stop . In our Applesoft program
example , a carriage return was inserted as indicated. This caused
the PRINT statement output in line 130 to be concatenated as
two separate numeric values.
Whenever you wish to output a number of items via the PRINT
statement to different fields in the disk file, either separate
PRINT statements
should be used or each PRINT statement
parameter should be delimited with the return code character.
This
is illustrated in the following program lines:
130 PRINT 1 :PRINT 2:PRINT 3:PRINT 4:PRINT 5
or
100 D$ = CHR$ (4):E$ = CHR$ (13) :REM CTRL-D
IS ASCII 4; RETURN IS ASCII 13
130 PRINT 1; E$; 2; E$; 3; E$; 4; E$; 5
If you substitute these lines in the example, the following output
will appear :
