"DECODE" command generates output code based on comparison of 1st parameter with set of alternative values. Generator compares 1st parameter to each value one by one. If expr is equal to a value, generator returns the corresponding result. If no match is found, generator returns default, or, if default is omitted, returns nothing.
Command syntax has two forms
Syntax1
%decode<value:variant1:result1:variant2:result2:...:variantN:resultN:default result>
Syntax2
<decode>value<,>variant1<=>result1<,>variant2<=>result2<,>...<,>variantN<=>resultN<,>default result<enddecode>
Note - in short form you can not use keywords like <1>, instead you can use %1%.
Example
To generate correct string conversion function use the following code (note - generator constant <\> is used for template formating purpose only)
<decode>%.type%<,><\>
string<=>%.name%<,><\>
integer<=>IntToStr(%.name%)<,><\>
float<=>FltToStr(%.name%)<,><\>
/*ERROR - unsupported type %.type%*/<\>
<enddecode>
