Tally Genicom 6600 manual Multiple Repeat Commands

Multiple Repeat Commands

Incrementing or decrementing numbers and characters is similar to adding or subtracting numbers. Align the numers and/or letters vertically in columns and add or subtract each column. For example, K + 1 means to advance 1 character position from K to the next letter (i.e., K+1 = L and K-1 = J).

The following examples show how automatic increments (addition) and decrements (subtraction) apply to numeric and character fields:

0A 0 A9 0A (Operand)

+1 -1 +1 +11 (Operator)

0B 9 B0 1B (Answer)

In automatic incrementing and decrementing, the alphabet wraps around itself, meaning that A is one character position beyond Z. The normal arithmetic rules of carrying or subtracting a 1 from other columns when adding or subtracting also apply. For example:

0Z 1B (Operand)

+1 -2 (Operator)

1A 0Z (Answer)

Below are two additional examples showing how this carry function operates:

0T 0A (Operand)

+17 +27 (Operator)

2A 2H (Answer)

The answer is always limited to the total number of characters and spaces in the operand, even if the operator value has the full twelve characters allowed. For example:

Y 2F 16A (Operand)

+112 -105 +1234 (Operator)

A 2A 39E (Answer)

If spaces are included in the operand value, only numeric values can appear in the answer for those same columns. No letters are permitted. For example:

(1 space) Y 2F (Operand)

+112 -105 (Operator)

2A 2A (Answer)
