* IN: * |
| 23 |
* IACT, integer specifing the action to be taken. It is the INWVOL * |
| 24 |
* variable in GCTRAK common * |
| 25 |
* IS , set number * |
| 26 |
* ID , detector number * |
| 27 |
* IPA , particle number * |
| 28 |
* IT , track number * |
| 29 |
* DELOSS, energy loss in the step * |
| 30 |
* PATH , current track lenght * |
| 31 |
* TRAPAR, track parameter, is the VECT vector in GCTRAK common * |
| 32 |
* NUMVOL, integr array of numbers identifying the DETECTOR * |
| 33 |
* IMEC , integer indicating the LOSS mecanism position inside NMEC * |
