8.2.14 Goto

G[OTO] postcond SP L gotoargument

Goto is a generalized transfer of control. If provision for a return of control is desired, Do may be used.

Each gotoargument is examined, one at a time in left-to-right order, until the first one is found whose postcond is either absent, or whose postcond is present and its tvexpr is true. If no such gotoargument is found, control is not transferred and execution continues normally. If such a gotoargument is found, execution continues at the left of the line it specifies, provided that the following conditions hold for the line containing the Goto command and the line specified by the gotoargument:

1. they have the same LEVEL, and
2. if that LEVEL is greater than one they
   1. must have no lines of lower execution LEVEL between them, and
   2. must be in the same routine.

If either A or B is not met, an error occurs with ecode = "M45".
