CALL 57 will transfer data from the MVI56-BAS output buffer to a CLX data file
using a Class 3 Message. In order to accomplish this, ladder logic is required
The following BASIC program transfers data to the output buffer using CALL 24
and executes CALL 57:
1 REM CALL 57
10 FOR I=100 TO 149
30 PUSH 200-I: REM VALUE TO BE TRANSFERRED
40 PUSH I: REM ADDRESS IN OUTPUT BUFFER
50 CALL 24
60 NEXT I
70 PUSH 50: REM NUMBER OF WORDS TO BE TRANSFERRED
80 CALL 57:
90 POP S: REM CALL 57 RESULT
130 END
