RSET
Field of Application Statement for placing data right-justifi ed into a fi eld in a random
fi le buffer.
Syntax RSET<svar>=<sexp>
<svar> is the string variable assigned to the fi eld by a FIELD
statement.
<sexp> holds the input data.
Remarks
After having OPENed a fi le and formatted it using a FIELD statement,
you can enter data into the random fi le buffer using the RSET and LSET
statements (LSET left-justifi 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 by the use of a STR$
function before an LSET or RSET statement is executed.
If the length of the input data is less than the fi eld, the data will be
right justifi 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 fi eld, the input data
will be truncated on the left 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 "
