LSET
Field of Application
Statement for placing data left-justi ed into a eld in a random
le buffer.
Syntax LSET<svar>=<sexp>
<svar> is the string variable assigned to the eld by a FIELD
statement.
<sexp> holds the input data.
Remarks
After having OPENed a le and formatted it using a FIELD statement,
you can enter data into the random le buffer using the LSET and RSET
statements (RSET right-justi es the data).
The input data can only be stored in the buffer as string expressions. Therefore,
a numeric expression must be converted to string format by the use of an STR$
function before an LSET or RSET statement is executed.
If the length of the input data is less than the length of the eld, the
data will be left justi ed and the remaining number of bytes will be
printed as space characters.
If the length of the input data exceeds the length of the eld, the input data
will be truncated on the right side.
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 "
NEW
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$
RUN
yields:
