===Elaborations on GO TO===
A compiler may offer the "assigned GO TO" facility, with statements such as <code>ASSIGN 120 TO THENCE</code> scattered about: 120 is a statement label, not an integer, and any statement label may be assigned to variable THENCE (which is an integer variable) as execution proceeds.
Aside from facilitating the production of spaghetti code, this sort of behaviour actually can be put to a positive use to handle the situation where in a large programme there may be portions that could be employed from a number of locations, and one does not wish to repeat that code each time - apart from the tedium of punching additional cards, each replication would demand its own unique set of statement labels. Further, such replication increases the total code size and memory is limited... <lang Fortran> ...
