Your custom types are based on these EGL classifiers:
Contents
Delegate
Enumeration
The following enumeration defines three possible values. See the example program for using this enumeration.
enumeration colorEnumeration RED, GREEN, BLUE end
ExternalType
Handler
Interface
The following Interface type reflects the MyService type shown in Service: Interface IMyService Function calculate(theList INT[] IN) returns(BIN (4,2)); // other function prototypes are here end
Library
Program
This basic program uses the sample enumeration.
program prog function main() test(colorEnumeration.RED); end function test(color colorEnumeration) case (color) when(colorEnumeration.RED) syslib.writestdout("red"); when(colorEnumeration.GREEN) syslib.writestdout("green"); when(colorEnumeration.BLUE) syslib.writestdout("blue"); otherwise syslib.writestdout("unknown"); end end end
Record
Service
Service MyService // variables and constants can be here function calculate(myScore Int[] in) returns (Decimal (4,2)) numberOfScores, i, mySum Int; numberOfScores = myScore.getSize(); for (i from 1 to numberOfScores by 1) mySum = myScore[i] + mySum; end return(mySum/numberOfScores); end // other functions are here end
