22 | * Usage notes: | |
23 | * This input module reads .ad files created using the | |
24 | * following practice commands: | |
25 | * | |
26 | * I.SAVE <file> /NoCompress | |
27 | * IPROBE.SAVE <file> /NoCompress | |
28 | * | |
29 | * It currently cannot make use of files that have been | |
30 | * saved using /QuickCompress, /Compress or /ZIP. | |
31 | * As a workaround you may load the file in PowerView | |
32 | * using I.LOAD / IPROBE.LOAD and re-save using /NoCompress. | |
