EDT:Writing statements
Revision as of 12:09, 13 February 2012 by Margolis.us.ibm.com (Talk | contribs)
EGL provides general statements, as well as statements that are used for interacting with an external data source.
General statements
Case
The case statement never runs more than one clause:
- You can test a criterion value. The following example invokes
mySecondFunction
:
function test() x Int = 3; case (x) when (1) myFirstFunction(); when (2, 3, 4) mySecondFunction(); otherwise myDefaultFunction(); end end
- You can test a set of logical expressions. The following example displays only "x passes":
function test() x Int = 3; y Int = 5; z Int = 7; case when (x == 3) SysLib.writeStdOut("x passes"); when (y == 5) SysLib.writeStdOut("y passes"); when (z == 7) SysLib.writeStdOut("z passes"); otherwise SysLib.writeStdErr("You will not see this message."); end end end
