X[ECUTE] postcond SP L xargument

expr postcond @ expratom V L xargument |
│ │ │ |
Xecute provides a means of executing M[UMPS] code which arises from the process of expression evaluation.
Each xargument is evaluated one at a time in left-to-right order. If the postcond in the xargument is present and its tvexpr is false, the xargument is not executed. Otherwise, if the value of expr is x, execution of the xargument is executed in a manner equivalent to execution of Do y, where y is the spelling of an otherwise unused label attached to the following two-line subroutine considered to be a part of the currently executing routine:
y ls x eol
ls Quit eol
