XECUTE

1977 Version of ANSI Standard

☞

3.6.19 XECUTE

X[ECUTE] postcond Space L xargument

    xargument::= │

│		 expr postcond
@ expratom V L xargument 		│
│
│

XECUTE provides a means of executing MUMPS code which arises from the process of expression evaluation.

Each xargument is executed one at a time in left-to-right order. If the postcond in the xargument is false, the xargument has no effect. Otherwise, if the value of expr is x, execution of the xargument is 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
