What is the pattern and – even more machine bending  important – why is it significant? Each set of vari ables


(seven sets listed above) contains variable numbers that differ by the amount of twenty First set


starts with sys tem vari able #5201, the sec ond set with sys tem vari able #5221, the third set with


sys tem vari able #5241, and so on The seven sets cover one ex ter nal work off set and six stan dard


work off sets, G54-G59 Ad di tional sets (G541 se ries), if avail able, use the same num ber ing


logic, but the vari ables num ber ing starts at #7001


In mac ros, it is of ten im por tant to ad dress these sys tem vari ables in an or ga nized way, with


some log i cal and ef fi cient ap proach Tak ing ad van tage of the in cre ments like 1 or 20, macro de –


vel op ment can use loops with coun ters, if re quired


The fol low ing ta ble con veys the same in for ma automatic punching machine tion as the seven lines above, per haps even better,


but is with out de scrip tions:
