An EGL assignment copies data from one area of memory to another and can copy the result of a numeric or text expression into a source field.
The behavior of an EGL assignment statement is different from that of a move statement; for more information, see move
For information about assignment rules, see Assignment compatibility in EGL.
Each of the following EGL statements is an assignment:
z = a + b + c; myDate = vgVar.currentShortGregorianDate; myUser = sysVar.userID; myRecord01 = myRecord02; myRecord02 = "USER";
a = a + b
The following table shows the complex assignment operators available in EGL.
Operator | Meaning |
---|---|
a += b | a = a + b |
a –= b | a = a – b |
a *= b | a = a * b |
a /= b | a = a / b |
a **= b | a = a ** b |
a %= b | a = a % b |
a |= b | a = a | b |
a &= b | a = a & b |
a xor= b | a = a xor b |
a ::= b | a = a :: b |
a?:= b | a = a ?: b |
