GET*
The GET# retrieves data from the disk, one character at a time.
FORMAT FOR THE GET* STATEMENT:
GETS fileS, 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 BASIC error message if string data is received where a number was requested,
but not vice-versa.
EXAMPLES OF GETS STATEMENT:
GETS 5, AS
GETS A, BS, C$, D$ —-^-^^--^-^-^-^-^-^-^
^ _( You can get more than 1 character at a time )
GET#5, A
The GET# statement is extremely useful when examining files with unknown con
tents like a file that may have been damaged by an experimental program. It is safer
than'lNPUTS because there is a limit to the number of characters allowed between
separators of INPUT variables." 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";FS
20 INPUT "FILE TYPE";TS
30 TS = LEFTS {T$,l> _ ,„
40 IFTS<>"S" THEN IFTS<>"P" THEN IF TS<>"U"THEN20
