GET
Field of Application Statement for reading a record from a random fi le to a random buffer.
Syntax GET[#]<nexp
1
>,<nexp

>
# indicates that whatever follows is a number. Optional.
<nexp
1
> is the number assigned to the fi le when it was OPENed.
<nexp
2
> is the number of the record. Must be ≠ 0.
Remarks
The GET statement is used to read a certain record in a certain random fi le
to a buffer, where the record will be assigned to variables according to the
FIELD statement given for the buffer. After the GET statement has been
executed, you can use references to the variables defi ned by the FIELD
statement to read the characters in the random buffer.
Numeric expressions, which have been converted to string expressions by
STR$ functions before being put into the buffer, can be converted back to
numeric expressions using VAL functions.
Example 10 OPEN "PHONELIST" AS #8 LEN=26
20 FIELD#8,8 AS F1$, 8 AS F2$, 10 AS F3$
30 SNAME$="SMITH"
40 CNAME$="JOHN"
50 PHONE$="12345630"
60 LSET F1$=SNAME$
70 LSET F2$=CNAME$
80 RSET F3$=PHONE$
90 PUT #8,1
100 CLOSE#8
RUN
SAVE "PROGRAM 1.PRG "

10 OPEN "PHONELIST" AS #8 LEN=26
20 FIELD#8,8 AS F1$, 8 AS F2$, 10 AS F3$
30 GET #8,1
40 PRINT F1$,F2$,F3$

yields:
