ELSEELSEClause of block-oriented IF command.ELSE { code_block }Refer to IF command.DescriptionELSE is not a separate command, but a clause of the block-oriented IF command. Refer tothe IF command for details.Note:An earlier version of the ELSE command may exist in legacy applications where itis used with a line-oriented IF command. These commands may be recognizedbecause they do not use curly braces. The old and new forms of IF and ELSE aresyntactically different and should not be combined; therefore, an IF of one typeshould not be paired with an ELSE of the other type.The earlier line-oriented ELSE command could be abbreviated as E. The block-orientedELSE keyword cannot be abbreviated.The ELSE keyword must be followed by an opening and closing curly brace ({) and (}).Usually these curly braces enclose a block of code. However, an ELSE with no code blockis permissible, as in the following:SET x=1LoopIF x=1{WRITE "Once only"SET x=x+1GOTO Loop}ELSE{}WRITE !,"All done"There are no whitespace restrictions on the ELSE keyword.See Also• IF command• IF (legacy version) command• Flow Control Commands in Using Caché ObjectScriptCaché ObjectScript Reference 37
