![]() We renamed it, as the instructions recommend, but, as we noted before, we were already well outside the lines of the sort of software we were looking for - or that most users would look for, for that matter. The program's executable file downloads with the (-k) suffix, which tells the Command Prompt to stay open. ExifTool popped back up with all of the image's available metadata displayed (many spaces were blank). Following the instructions, we closed the prompt and dragged an image file into ExifTool's executable. Right away we knew we were in unfamiliar territory. We extracted ExifTool's executable and double-clicked it to open the program's documentation, which includes an extensive list of file types and meta information formats that ExifTools supports. To edit data, you'll need to rename the executable file and open it via a command line, which enables all of the Perl distribution's features. Simply place this portable tool's executable file on your desktop and drag an image file into it to produce a Command Prompt window displaying all of the file's available metadata. All output was to disk, computer line flow reports or forms (invoices, cheques, etc).If you can handle the Perl programming language or have no problem with the Command Prompt (or typing characters and spaces) then ExifTool offers a super-fast way to view and edit an image file's metadata without having to open a substantial program. A major upgrade made batch processing on 4 parallel streams possible. There was a basic screen for the single computer operator. Everything was batch, no such thing as a GUI. ![]() Unfortunately, some superb assembler programmers were not able to make this transition. Moving to "4th Gen " language with compilers and data entry direct to disk was in serious sci-fi territory. I had to learn assembler from a single large assembler reference manual. There was no training course for any of this. ![]() The punched paper tape roll was then read into the target computer and saved to magnetic tape. The memory was then dumped to a punched tape. ![]() This code was manually inserted into the computer memory with a special keyboard to memory utility on a data prep machine. Memory locations had to be manually calculated. I then had to manually convert it to machine code. One of the first serious programs I wrote was first coded in assembler. ![]()
