NOCONVERT
Syntax
NOCONVERT {OFF | ON}
Description
The UniBasic NOCONVERT command controls the conversion of the special
character CHAR(0). The following UniBasic commands read and write non-UniData
files or tapes and convert CHAR(0) to CHAR(128) on input. They also convert
CHAR(128) to CHAR(0) on output. This can cause problems under some circumstances,
especially if you use the character CHAR(128) in an application or in stored
data. NOCONVERT provides a way of switching the conversion OFF or ON. The
default is OFF.
The following UniBasic commands convert CHAR(0) and CHAR(128) when
NOCONVERT is turned on:
OSBREAD, OSBWRITE, OSREAD, OSWRITE, READT, WRITET
Note: The PRINT and CRT functions do not work with strings that contain CHAR(0).
Warning: Do not use UniBasic READ and WRITE commands to open or modify
binary data in DIR-type files (for example, BP). Doing so can corrupt data in the file.
Instead, use OSREAD or OSBREAD after executing the UniBasic NOCONVERT
command.
The following functions work with strings containing CHAR(0), regardless of the
setting of the NOCONVERT command:
Assignment (X = Y)
Bracket function ([])
Substring assignment (A[1,3] = B)
String concatenation (A:B)
CHAR
CONVERT
COUNT
