How many elements in a CASE ?

[cyrille de brébisson]

Hello,

C/C++ is typed, so when you do a switch/case, the compiler knows what the input type is, and the case are constant. This allows the compiler to generate a jump table...

in HPPL, the variables are not typed, and the case statements can be much broader... This forces a sequential scanning of the cases.

Here, the internal 'counter' is limited to 8 bits, and each case takes 2 items: the test part and the evaluate if ok part. Therefore the limit...

It was thought at the time that the 127 limit would not be a problem as a program that needed more was most likely not correctly implemented (for the structure of HPPL).
