Here is a picture of the file after the statement PRlNT# 5, I; 3; 5; 7 is

performed:

Appendix B contains a program demonstrating the use of a sequential disk

GET#

The GET# retrieves data from the disk, one character at a time.

FORMAT FOR THE GET# STATEMENT:

GET# f1le#, variable list

Data comes in byte by byte, including the CR, comma, and other

separating characters. It is much safer to use string variables when using the

GET# statement. You will get a BASICerror message if string data is received

where a number was requested, but not vice-versa.

EXAMPLES OF GET#STATEMENT:

GET# 5, A$

You can get more than I character at a time

GETS 5, A

The GET# statement is extremely useful when examining files with

unknown contents, like a file that may have been damaged by an experimental

program. It is safer than INPUT# because there is a limit to the number of

characters allowed between separators of INPUT variable.s.With GET#, you

receive every character, and you can examine separators as well as other data.

Here is a sample program that will allow you to examine any file on the

disk:

10 INPUT "FILE NAME"; F$

20 INPUT "FILE TYPE";T$

30 T$=LEFTS(TS,1)

40 IF TS < > "s" THEN IF T$ < > "P" THEN IF T$ < > "u" THEN 20

45 OPEN 15,8,15

50 OPEN 5,8,5, "0:" + F$+ ","+ T$+ ",R"
