- Input Procedure
Although interrupt branching using ON INT can be used in almost all situations,
TRANSFER is useful when you need to perform input time monitoring (SET
TIMEOUT/ON TIMEOUT) processing. Normally, interrupt input using ON INT is
used.
Data is output into the input/output buffer first and then read using ENTER.
Common variables cannot be used in the input/output buffer.
10 DEFINT I
20 DIM BUFF$ 256,A$256
30 ASSIGN RS22=5
40 ON EOT 5,2 GOSUB RSEOT@ … Specify interrupt destination
50 TRANSFER 5,2 INTO BUFF$ … Initiate TRANSFER
Other processing
1000 RSEOT@ STATUS 5,2,4;IST
1010 IF IST<>0 THEN
1020 PRINT “TRANSFER ERROR!”
1030 ELSE Interrupt processing for end of
TRANSFER
1040 ENTER BUFF$;A$
1050 PRINT A$
1060 ENDIF
1070 RETURN

Format Specification
When specifying the format such as the addition of terminator in a TRANSFER
statement, match it with the format specification of the ENTER/OUTPUT statement used
for buffer input/output.
For details on the operation of each individual format type, see Section 4.2.
