Is there a way for a running program to access the output of commands such as "MEMORY" or "LIST FUNCTIONS" and similar? Could it become so? It's not immediately obvious how that would work though. For example, "MEMORY" outputs 8 lines of information. a$ = MEMORY kind of makes sense, but of course doesn't work. a$ = LIST COMMANDS could never work because the output is more than 255 characters. One possibility might be MEMORY, #nbr, where nbr is an open file. This could apply to any command that outputs text, sending the output to a file on disk instead of the screen.

A possible syntax: LONGSTRING APPEND ls%(), EXECUTE MEMORY LONGSTRING APPEND ls%(), EXECUTE LIST COMMANDS LONGSTRING APPEND ls%(), EXECUTE PRINT somethingcomplex Whatever output results from the EXECUTE goes into the long string. ~ Edited 2020-12-21 08:23 by lizby PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |

@lizby I too would love to have the ability to "pipe" the output that goes to the console to a file (or longstring). The functionality to output commands to a file already exist with commands like PRINT #1,"something". Thus adding the functionality to EXECECUTE could take the form OPEN filename FOR output AS #1 EXECUTE #1,"some command" ' such as MEMORY, FILES etc CLOSE #1 Thus any output that would normally go to the console could be captured to file.

Well, I think I've found an idiotic method of doing this! It uses OCR, sort of. Fortunately, MEMORY, LIST, LIST FUNCTIONS, etc respect the settings of both PAGE WRITE and FONT. The following program uses a custom font that is the binary representation of the ascii code. Then it is a simple matter of PEEKing 8 bytes in the appropriate page to recover the character that was 'printed' there. The following example does not use page write, mainly so you can see what it did. Also, the output is limited to the page height, so 600ish lines in MODE 1, but mode 9 or a tall FRAMEBUFFER would allow more. mode 1,8 cls font 10 '======================================== ' Put your command to capture output here 'list functions memory '======================================== font 1 print @(0,200) memloc% = MM.INFO(PAGE ADDRESS 0) x% = 0 y% = 0 zero = 0 print "line #1: "; do b = 0 ' examine 8 pixels to rebuild ascii for i = 1 to 8 b = b * 2 + (peek(byte memloc% + 800 * y% + x%) <> 0) x% = x% + 1 next i if b = 0 then ' end of line? x% = 0 y% = y% + 1 zero = zero + 1 print "line #" str$(y%+1) ": "; else print chr$(b); zero = 0 endif loop until zero = 4 ' done when 3+ blank lines found '======================================== ' BinaryOCR.fnt by vegipete ' 8 pixels wide by 1 pixel high ' CHR$( 32) = 00100000 ' to ' CHR$(127) = 01111111 ' DefineFont #10 60200108 23222120 27262524 2B2A2928 2F2E2D2C 33323130 37363534 3B3A3938 3F3E3D3C 43424140 47464544 4B4A4948 4F4E4D4C 53525150 57565554 5B5A5958 5F5E5D5C 63626160 67666564 6B6A6968 6F6E6D6C 73727170 77767574 7B7A7978 7F7E7D7C End DefineFont Visit Vegipete's *Mite Library for cool programs. |

That's idiotic. And pretty clever. This is the type of thing that programmers did in the 80s just because it was the only possible way for them to get what they need. I doubt I ever would have thought of this. Edited 2020-12-22 05:17 by CircuitGizmos Micromites and Maximites! - Beginning Maximite |

We called it screen scraping. I used to take screen print files from one system and produce MS-Access reports for our accounting department. It was simple but tedious work to get all the reports off the screens but it was the only way to interface our mainframe with our PCs. |
