'BX' System Parameter

     BBx Emulation

Description

Sets ProvideX to BBx emulation mode. This automatically resets certain system

parameters to behaviour required to run programs designed for BBx.

Note: Use the 'LZ' Suppress Leading Zeros, p.671, to control rounding of leading

zeros. (This functionality was previously controlled by the 'BX' parameter.).

The following parameters are affected by the 'BX' parameter: 'AD', 'B0', 'BT', 'BY'=,

'CD', 'DC', 'EX', 'FF'=, 'I0', 'JC', 'KR', 'MP', 'NR', 'OP', 'QS', 'RS', 'WK', 'XF'. For WindX

environments, this parameter must be set on both the client and the server.

Default

Off. ProvideX is in standard mode ('FF'=0).

'BY'= System Parameter

  Base year

Description

Defines the base year for the JUL( ) Function, p.461, and the DTE( ) Function, p.420.

Default

'BY'=1970.

Note: The JUL( ) function uses January 1 of the base year as day 0 zero.

Also: If you SET_PARAM 'BY'=0 zero, the JUL( ) and DTE( ) functions operate under

the Julian calendar where day 0 is around 4713 BC.

'CD' System Parameter

     Check Current Directory

Description

Checks the current directory first before checking the prefix list for a file.

Default

Off. Searches current directory after the prefixes (normal method).

'CE' System Parameter

   Obsolete

Description

Deprecated. Use the 'NE' System Parameter, p.673.

'CF' System Parameter

     Bypass Console Flush

Setting

PVX UNIX/Linux Only. Bypasses console flush for print statements. Use 'CF' to

improve display performance (i.e., no waiting for OS acknowledgment after every

PRINT statement).

Default

Off. Performs a console flush on print statements.
