Hello all,
The standard Pascal (ISO 7185) doesn't have a
'return' statement, so a function or procedure will
execute to the end. I often encounter situations in
which multiple sequential checks must be done so
that:
a. the failure of one check interrupts the whole
sequence and
b. each seccessive check may use the result cal-
culated in the previous check.
This can be represented like many nested IF state-
ments, which is ugly when the nesting level is high.
Languages with a non-structured 'return' statement
allow to linearize this, but what to do in Pascal?
I thought about looping through an array of fucntion
pointers, but this seems too much of an overhead to
me...
Thank you in advance,
Anton
