Parameter string

All 4 basic arithmetic operations are permissible in any sequence. A parameter string is limited
by the block length of 120 characters maximum.
R1=R2+R3 – R4·R5 / R6......
The calculations are performed as follows:
Step 1 R1 = R2
Step 2 R1 = R1+R3
Step 3 R1 = R1–R4
Step 4 R1 = R1·R5
Step 5 R1 = R1 / R6
Step 1
Step 2
Step 3
Instead of a logical R parameter (not a result parameter), constants and pointers (pointers to R
parameters) are allowed with address P in the parameter string.
Example:
R1=R2+10.5 – P3·R5 / R6...
The result parameter must be an R parameter.
P3:
P Address of pointer
3 Pointer to R parameter R3, i.e. the contents of R3 are the address of an R parameter
whose value is included in the parameter string.
Any number of arithmetic operations may be performed in a block, e.g.
multiplication, parameter string, addition, etc.; the maximum permissible
block length of 120 characters must not however be exceeded. The
individual operations are performed in the programmed sequence.
