undocumented Len function - Jack - 08-16-2024 in the Wiki the Len function is described for strings only but QBasic uses the Len function also to get the size in bytes of data types including udts but QB64pe also gives the size in bytes of an array, but this seems to be a feature and it behaves strangely the following works and prints 50, 100 and 200 Code: (Select All)
but if you add the followingCode: (Select All)
it prints 100 instead of 2, the division never takes placeI think that getting the SizeOf an array would be nice to have and it almost works, perhaps the developers could fix it so that the last statement would be evaluated correctly RE: undocumented Len function - SMcNeill - 08-16-2024 Looks like a bug in the processing to me: Code: (Select All)
RE: undocumented Len function - RhoSigma - 08-16-2024 Definitly a very old bug then, QB64 v0.954 (last SDL based version) behaves the same way. RE: undocumented Len function - Jack - 08-16-2024 actually, I think that the Len of an array is an unintentional feature, it not supported by QBasic but it's so close to working in QB64pe that it would be a shame not to fix it |
