Meaning Statement example
The right side is P1=P2
substituted in the left P5=P_Curr
side. P10.Z=100.0
M1=1
STS$="OK"
Add P10=P1+P2
Mov P8+P9
M1=M1+1
STS$="ERR"+"001"
Subtract P10=P1-P2
Mov P8-P9
M1=M1-1
Multiply P1=P10*P3
M1=M1*5
Divide P1=P10/P3
M1=M1/2
Exponential operation M1=M1^2
Integer division M1=M1\3
Remainder operation M1=M1 Mod 3
Sign reversal P1=-P1
M1=-M1
Compare whether If M1=1 Then *L1
equal If STS$="OK" Then *L2
Compare whether not If M1<>2 Then *L3
equal If STS$<>"OK" Then *L4
Compare whether If M1< 10 Then *L3
smaller If Len(STS$)<3 Then *L4
Compare whether If M1>9 Then *L3
larger If Len(STS$)>2 Then *L4
Compare whether If M1<=10 Then *L3
equal to or less than If Len(STS$)<=5 Then *L4
Compare whether If M1=>11 Then *L3
equal to or more than If Len(STS$)>=6 Then *L4
