Decreases tend to be more common in form programmes than increases. The following table shows several ways to do decreasing. I have found other codes that do decreases, but I haven't figured them out yet. The amount to decrease is calculated using a rather odd formula: subtract 121 from the value given. 121 seems very arbitrary, but it also consistent across all form programmes I've seen.
| Shaping Code | Example | Commentary |
|---|---|---|
| 184 or 185 | 185 141 | Decrease 20 stitches at once. (141 - 121 = -20) |
| 186 | 186 141 | Decrease 20 stitches by breaking it up into 2 batches of decreases of 10 each. (141 - 121 = 20; -10 - 10 = -20) |
| 187 | 187 141 | Decrease 20 stitches by breaking it up into 3 batches of decreases. (141 - 121 = 20; -7 - 7 - 6 = -20) |
| 188 | 188 141 | Decrease 20 stitches by breaking it up into 4 batches of decreases. (141 - 121 = 20; -5 - 5 - 5 - 5 = -20) |
| 189 | 189 141 | Decrease 20 stitches breaking it up into 5 batches of decreases. (141 - 121 = 20; -4 - 4 - 4 - 4 - 4 = -20) |
| 190 | 190 141 | Decrease 20 stitches breaking it up into 6 batches of decreases. (141 - 121 = 20; -4 - 4 - 3 - 3 - 3 - 3 = -20) |
| 191 | 191 141 12 | Decrease 20 stitches evenly over 10 centimeters. This is the decrease often seen in V-neck shaping. To calculate the vertical distance over which the decrease will take place, add 8 to the 3rd number in the sequence and divide by two. For example, 12 + 8 = 20; 20/2 = 10 centimeters. |
Increasing works similarly to decreasing, except of course that increasing adds stitches instead of taking them away. The amount to increase is calculated using a rather odd formula: subtract 121 from the value given. 121 seems very arbitrary, but it also consistent across all form programmes I've seen.
| Shaping Code | Example | Commentary |
|---|---|---|
| 56 or 57 | 57 141 | Increase 20 stitches at once. (141 - 121 = 20) |
| 58 | 58 141 | Increase 20 stitches by breaking it up into 2 batches of increases of 10 each. (141 - 121 = 20; 10 + 10 = 20) |
| 59 | 59 141 | Increase 20 stitches by breaking it up into 3 batches of increases. (141 - 121 = 20; 6 + 7 + 7 = 20) |
| 60 | 60 141 | Increase 20 stitches by breaking it up into 4 batches of increases. (141 - 121 = 20; 5 + 5 + 5 + 5 = 20) |
| 61 | 61 141 | Increase 20 stitches breaking it up into 5 batches of increases. (141 - 121 = 20; 4 + 4 + 4 + 4 + 4 = 20) |
| 62 | 62 141 | Increase 20 stitches breaking it up into 6 batches of increases. (141 - 121 = 20; 3 + 3 + 3 + 3 + 4 + 4 = 20) |
| 63 | 63 141 12 | Increase 20 stitches evenly over 10 centimeters. To calculate the vertical distance over which the increase will take place, add 8 to the 3rd number in the sequence and divide by two. For example, 12 + 8 = 20; 20/2 = 10 centimeters. |
This has been a detailed discussion of the PASSAP form programme. Alas, it is not a complete one. There are still several codes left unaccounted for.
It is my hope that this information will aid you in designing your own form programmes and modifying existing programmes. During my experiments I have occassionally gotten the console stuck on the wait message. If this happens to you and it doesn't clear up in a minute or so, just turn off the console and turn it on again after a few seconds. Then check your programme and make adjustments.
If you make any additional discoveries, I hope you will share them with me at support@passappal.com.
