'LU' System Parameter
Lock Unnecessary: Serial Files
Description
Makes lock unnecessary on writing to serial files. (No Error #13 on WRITE without
lock.)
Default
Off. A "sticky" parameter. ProvideX generates Error #13: File access mode
invalid if there is no lock on the first write to an open file number.
Note: File access mode is checked once, on the first write after opening. An error won't be
generated on a subsequent unlocked write if the file number is continuously open between
writes (even if the parameter is switched off between writes).

'LZ' System Parameter
Suppress Leading Zeros
Description
Suppresses leading zeros for numeric values. This was previously controlled by the
return value of 0.25. With 'LZ' enabled, the return value would be .25.
Default
Off.
'MB'= System Parameter
MegaBytes: File Segment Size
Description
Controls segment size in multi-segmented files. 'MB' must be set to a value to
activate the multi-segmented file feature. ProvideX calculates the approximate size
of each segment in megabytes, based on the block size of a file:
Segment size in bytes = 512 + ((bksz - 6) * bksz)
bksz above represents the block size of the file. You can use the BSZ=option when
you create the file, to override the default block size.
The following table lists the maximum number of segments allowed for a file based
on valid block sizes (1 to 31 kilobytes):
