OSREAD
Syntax
OSREAD var FROM filename [ON ERROR statements] {THEN statements [END]
| ELSE statements [END]}
Description
The UniBasic OSREAD command reads an entire sequential file and assigns the
contents of the file to a variable.
Warning: Do not use OSREAD on large files. If the file is too large for the program
memory, the program aborts and a runtime error message is generated. On large
files, use OSBREAD or READSEQ.
Note: UniData uses the ASCII 0 character [CHAR(0)] as a string-end delimiter.
ASCII 0 cannot be used in any string variable within UniBasic. OSREAD converts
CHAR(0) to CHAR(128) when reading a block of data.
Parameters
