Fast Tape Search

Move how many marks (-ve for backwards) ?

When using the VISS system to locate an index mark on the tape, the tape will be wound forwards or backwards from the current point until a specific number of index marks have passed. The value specified to this prompt specifies the number of index marks. If a negative value is specified, then the tape will be wound backwards (using REW) until the required index mark is found. Positive values invoke a FF operation until the required index mark is found. Note that if the required number of index marks are not detected, then DigImage may hang-up when it reaches the end of the tape. DigImage may be fooled into thinking the address has been found by manually pausing the tape. If this fails, then <escape> will generally abort the operation, but sometimes it may be necessary to abort DigImage using <ctrl><break>.
