GET_RECORD$
Purpose To get a record i
n a specified DBF file, which the file pointer of a specified IDX
file is pointing to.
Syntax A$ = GET_RECORD(file% [,index%])
Remarks “A$” is a string variable to be assigned to the result.
“file%” is an integer variable in the range of 1 to 5, indicati
ng which DBF file to
be accessed.
“index%
” is an integer variable in the range of 1 to 3, indicating which IDX file
to be accessed. If it is not specified, the default IDX file which keeps the
original data sequence will be used.
Example
ON COM(1) GOSUB BcrData_1
…
BcrData_1:
BEEP(2000, 5)
ID$ = GET_READER_DATA$(1)
IF FIND_RECORD(DBFNum%, IDXNum%, ID$) = 1 THEN
Data$ = GET_RECORD$(DBFNum%, IDXNum%)
Item$ = MID$(Data$, LEN(Data$)-IDLeng%-ItemLeng%)
Note$ = RIGHT$(Data$, LEN(Data$)-IDLeng%-ItemLeng%)
LOCATE 1, 1
PRINT “ID :”, Data$
LOCATE 2, 1
PRINT “Item :”, Item$
LOCATE 3, 1
PRINT “Note :”, Note$
ELSE

GET_RECORD_NUMBER
Purpose
To get the ordinal number of the record pointed to by the file pointer of a
specified DBF file and IDX file.
Syntax A% = GET_RECORD_NUMBER(file% [,index%])
Remarks “A%” is an integer variable to be assigned to the number.
“file%” is an integer variabl
e in the range of 1 to 5, indicating which DBF file to
be accessed.
“index%
” is an integer variable in the range of 1 to 3, indicating which IDX file
to be accessed. If it is not specified, the default IDX file which keeps the
original data sequence will be used.
Example
A% = GET_RECORD_NUMBER(1, 1)
