Assignments

Values of matching types can be assigned to
variables/arithmetic parameters in the program.
The assignment is always made in a separate block;
up to two assignments are possible per block.
Assignments to axis addresses (traversing
instructions) always require a separate block to
variable assignments.
Programming example
R1=10.518 R2=4 VARI1=45
X=47.11 Y=R2
R1=R3 VARI1=R4
R4=-R5 R7=-VARI8
Assignment to string variables
A distinction is made between upper and lower case
characters within a CHAR or STRING.
If ' or " are to be included in the character string,
these should be enclosed in '...'.
Example:
MSG("Viene lavorata l' ''ultima
figura")
displays the text 'Viene lavorata l'ultima figura' on the
screen.
Non-displayable characters can be stored in the
string as binary or hexadecimal constants.
