Whether you want to make a simple font with upper and lower case, numbers, and basic punctuation OR a fully featured font family with multiple language support, FontLab can definitely get you there.

It's an extremely powerful program and its has all the features necessary to make professional fonts. Depending on the application, this could work quite well.ĬP/M's file structure is sort of a happy medium, geared toward the floppy user.I am a graphic designer turned type designer and I've been using FontLab Studio for 7 or 8 years. Defragmentation/repacking the disk was usually done with separate utility. This gives you efficiency in access (no fragmentation) and reliability (no advanced structures other than a directory showing size and starting sector), but imposes a penalty with regards to being able to extend files. If you look at some competing operating systems in the CP/M era, allocation was contiguous, with each file being pre-allocated.

SC-DOS and MS-DOS came alone when hard disks were well established. Recall, also that CP/M was spawned in the early days of floppy systems hard disks were beyond the budget of most people and organizations. You gain a certain amount of efficiency and versatility by using a linked structure, but that same added level of complexity sets the stage for more serious problems when things don't go right. In short, CP/M structural errors are far less common that FAT filesystem ones. Unerase is pretty simple, as long as the original data hasn't been overwritten. Things such as missing extents are okay ("sparse" files are legal) as well as strange characters in file names. Usually, you lose only one block's worth of data in a file with such errors. Oddly, those aren't nearly as disastrous as FAT filesystem structural errors.

Over the years, I've discovered CP/M disks with out-of-range block numbers, and duplicate block numbers in the same file as well as two files sharing the same block number. But, as I said, CHKDSK doesn't normally do a surface analysis it just checks structure. Recovery of the media usually requires re-formatting (or else you must re-write the directory sectors with 0xe5).

If some errant code corrupts the in-memory ALV, CP/M may double-allocate blocks and even allocate directory blocks to a file - typically destroying the directory. When a disk is "logged in", CP/M will read all file entries and construct the in-memory allocation vector - to be used on subsequent file create/write operations. Just re-copying the files over a corrupted disk won't necessarily fix it - you must start with an empty directory. And, of course, success will depend on how much the disk was used while corrupted - as collateral damage can be severe. It will depend on the type of corruption. Unfortunately, there isn't a lot of information in a CP/M filesystem from which to reconstruct the directory. If you have a corrupted filesystem and are trying to repair it, one possibility is to image the filesystem onto a modern computer and use cpmtools - which has a 'fsck.cpm' and other tools. I seem to recall seeing some attempts to do that, but can't think of a specific example.
