| 5 $! Filter files for "#if" line continuations using a '\' and convert | |
| 6 $! them to use comments for the continuation. Necessary for VAXC - it | |
| 7 $! doesn't understand the '\'. | |

| 9 $! Yes, this is honkin' ugly code, but I deliberately avoided | |
| 10 $! if ... | |
| 11 $! then | |
| 12 $! .... | |
| 13 $! endif | |
| 14 $! and call/subroutine/endsubroutine constructs, because I can still | |
| 15 $! remember when DCL didn't have them, and I wanted this to be as | |
| 16 $! portable as possible, so... If you want to structure it nicer for | |
| 17 $! your own use, please feel free to do so. However, please only | |

18 $! distribute it in its original form. |
| 7 | 19 $! |
| 20 $! I wrote it in DCL for portability and ease of use - a C version | |
| 21 $! would definitely run faster, but then I'd have to deal with compiler | |
| 22 $! differences, and users would have to deal with configuring and | |
| 23 $! building it. With DCL, it runs out-of-the-box. | |
| 24 $! | |
| 25 $! Note that if you use this from a VMS system to modify files on a | |
| 26 $! mounted network drive, f$search() may return only the first matching | |
| 27 $! file when it tries to resolve wildcards. I have been unable to find | |
| 28 $! a way around this. Either copy the files to a local disk, or specify | |
| 29 $! each file individually (Keep in mind if you do this that VMS limits | |
| 30 $! you to eight parameters, so you'll only be able to filter eight files | |
| 31 $! at a time). | |
| 32 $! | |
| 33 $! Ideas... | |
| 34 $! - Use 'search filespec "#","if","\"/mat=and' to quickly eliminate | |
| 35 $! files that definitely don't need filtering. This should speed | |
| 36 $! things up considerable. Reading and writing every line from every | |
| 37 $! file takes quite a bit of time... | |
| 38 $! - Error handling isn't great. Come up with something better.... | |
