How to redirect Print output into a file

Folks,

 

just doing some research of my Apple IIe for example trying to readout PROM content of different cards. So far the following is working as expected

REM APPLE II - Reading PROM content out of 2 x (256x4 bipolar PROM) e.g. Slot 4 -> Address $C400 => 50176dec.1 REM $C000..C07F On Board Resources2 REM $C080..C08F Slot 0 /DEVSEL area (16 byte register file)3 REM $C090..C09F Slot 1 /DEVSEL area4 REM ... repeated for Slot 2..65 REM $C0F0..C0FF Slot 7 /DEVSEL6 REM $C100..C1FF Slot 1 /IOSEL area (256 bytes 'PROM')7 REM ... repeated for Slot 2..68 REM $C700..C7FF Slot 7 /IOSEL area9 REM $C800..CFFF Common area for all Slots (2 KiB 'ROM')10 INPUT "Enter PROMSTART Addr. (decimal)";PROMSTART20 FOR I = 0 to 25530 A = PEEK(PROMSTART+I)40 B = INT(A/16)50 A$ = MID$("0123456789ABCDEF",A-16*B+1,1) + A$60 A = B70 IF A > 0 THEN 4080 IF(LEN(A$)/2) > INT(LEN(A$)/2)THEN A$ = "0" + A$90 PRINT A$100 A$ = ""110 NEXT I

but I’m failing to redirect the printout into a file instead of printing it to the screen.

Can someone please point me into the right direction? My programming skills a for more then 40 years gone ;-)

You need to OPEN a file, then

You need to OPEN a file, then issue a WRITE command.

Many thanks... it’s probably

Many thanks... it’s probably not the best program code but it works ;-)

Well if we're going to get

Well if we're going to get picky -  In line 50 you use variable A$ which hasn't been initialized yet...
