LINE INPUT will now use the faster method if passed a file handle that has been opened FOR BINARY. As such, the _BLINEINPUT command has been removed. qb64.bas now takes advantage of this for reading from '$include files, at least in Include Manager 1. Some tweaking of internal/source/main.txt was required to get things into a sane state, so I'm holing off changing the compiler any further so the auto-builder can make sure everything's smoothed over. Note: Everything should still compile as normal; I'm just being overcautious.

|
|
* Any string expression returns the size, in bytes, of free string storage space.
|
|
* Also compacts the free string storage to a single block of memory.
|
|
* 0 returns the same value as using a string expression above.
|
|
* -1 returns the size of the largest non-string array in bytes that could be dimensioned.
|
|
* -2 returns the amount of stack space, in bytes, available to a running program.
|
|
* Any other numerical value returns the size of the next block of string memory storage space.
