DECODE
Purpose： To perform barcode decoding.
Syntax： DECODE
Example： ENABLE READER(1)
…
MAIN:
IF DECODE <>0 THEN
CLS
LOCATE 0,0
A$=GET_READER_DATA$(1,4)
PRINT "DATA:"+A$
LOCATE 0,2
A$=GET_READER_DATA$(1,1)
PRINT "Name:"+A$
LOCATE 0,4
PRINT "Length:",GET_READER_DATALEN
LOCATE 0,6
A$=GET_READER_DATA$(1,2)
PRINT "FULL:"+A$
LOCATE 0,8
PRINT "ID:"+GET_READER_DATA$(1,3)
END IF
IF INKEY$=CHR$(27) THEN
DISABLE READER(1)
END
END IF
GOTO MAIN
Description： Once the scanner port is initialized (by using ENABLE
READER command), call this DECODE command to
perform barcode decoding. This command should be called
constantly in user's program loops when barcode decoding is
required. If the barcode decoding is not required for a long
period of time, it is recommended that the scanner port be
disabled by using DISABLE READER command.
