Delimiters mark the beginning and end of an entity. EGL uses the
following delimiters:
- quotation marks " "
- Quotation marks in EGL always enclose a STRING literal.
- braces { }
- Braces can enclose any of the following things:
- Property value assignments, as in the following example:
username STRING {inputRequired = YES, upperCase = YES};
- Initial value assignments for record fields, as in the following
example:
record CustomerRecord type BasicRecord {
customerNumber=0,
customerBalance=0}
customerNumber INT;
customerBalance MONEY;
end
- Initialization for variables (usually with arrays), as in the
following example:
myStringsInit string[2] {"Hello", "Goodbye"};
- Any combination of the above. Set variables or fields first, then
properties:
myDecimals decimal(10,2)[3] {55.43, 22.12, 4.34, CurrencySymbol = "$"};
- brackets [ ]
- Brackets can enclose any of the following things:
- parentheses ( )
- Parentheses can enclose any of the following things:
- The parameters, arguments, or return values of a function, as
in the following example:
function testFunction1(myInt INT in) returns(INT)
return(5);
end
function testFunction2()
testFunction1(12);
end
- Parts of an expression to be evaluated first, as in the following
example:
newVar INT = (5-2)*4;
- The range of a variable (required for certain types), as in the
following example:
newDecimal DECIMAL(10,2);
- Negative numbers in a mask, as in the following example:
result = strLib.formatNumber(myNum,"(*,***,###.##)");
