INPUT:vectors

making_corrections

 If you want to change a previous entry, say the n'th entry, enter In
 before the new entries.  All entries must be present. For example,
 suppose you are creating 3 vectors, X, Y, and Z, and when entering the
 4th set of numbers, you realize you have made a mistake in the 2nd
 entry. The following example shows how you could correct the mistake.

 PHYSICA: INPUT X Y Z
 Enter 3 numbers, ( CTRL-Z ends )
 (  1) >> 10 .1 1000
 (  2) >> 20 2 2000
 (  3) >> 30 .3 3000
 (  4) >> I2 20 .2 2000
 (  4) >> 40 .4 4000
 (  5) >> 50 .5 5000
