A boolean type. Values aretrue andfalse.

For example:

setberesp.cacheable=true;

Integer literals may not be used to assign to a BOOL variable.

Likewise there is no implicit conversion to INTEGER types:

declare local var.iINTEGER;
declare local var.bBOOL;
set var.b=true;
set var.i=0;
set var.i+= var.b;/* invalid */

Nor may STRING literals be used for assignment (i.e."true" rather thantrue), however BOOL values may be converted to a STRING, and are renderedas"1" and"0" fortrue andfalse respectively:

declare local var.bBOOL;
set var.b=true;
log var.b;/* equivalent to "1" */
