Hi agama...

No, I hadn't even thought about an array but I tried your code and now it is near instant...
(Macbook Pro, 13", circa August 2012, default is bash.)

This has helped me no-end and now I have to apply it to the frequency counter...
When it is inside the frequency counter code you will be mentioned...

If I couldn't find an alternative to my original code then I WAS going to spawn a child process and pass the results back to the parent code in its own time...

Many, many thanks...

@ Don...
Using ksh and your snippet shaved 6.5 seconds off of my original code...

@ alister...
Thanks for the heads up I will take careful note although I am sure Corona688 mentioned this problem to me some time ago...

Thanks to all for your time...

Bazza...

ODBC_BINMODE(3) 							 1							   ODBC_BINMODE(3)

odbc_binmode - Handling of binary column data

SYNOPSIS
bool odbc_binmode (resource $result_id, int $mode) DESCRIPTION
Enables handling of binary column data. ODBC SQL types affected are BINARY, VARBINARY, and LONGVARBINARY. When binary SQL data is converted to character C data, each byte (8 bits) of source data is represented as two ASCII characters. These characters are the ASCII character representation of the number in its hexadecimal form. For example, a binary 00000001 is converted to "01" and a binary 11111111 is converted to "FF". LONGVARBINARY handling +----------------------+----------------+---+ | binmode | | | | | | | | | longreadlen | | | | | | | | result | | | | | | +----------------------+----------------+---+ | | | | |ODBC_BINMODE_PASSTHRU | | | | | | | | | 0 | | | | | | | | passthru | | | | | | | | | | | ODBC_BINMODE_RETURN | | | | | | | | | 0 | | | | | | | | passthru | | | | | | | | | | |ODBC_BINMODE_CONVERT | | | | | | | | | 0 | | | | | | | | passthru | | | | | | | | | | |ODBC_BINMODE_PASSTHRU | | | | | | | | | 0 | | | | | | | | passthru | | | | | | | | | | |ODBC_BINMODE_PASSTHRU | | | | | | | | | >0 | | | | | | | | passthru | | | | | | | | | | | ODBC_BINMODE_RETURN | | | | | | | | | >0 | | | | | | | | return as is | | | | | | | | | | |ODBC_BINMODE_CONVERT | | | | | | | | | >0 | | | | | | | | return as char | | | | | | +----------------------+----------------+---+ If odbc_fetch_into(3) is used, passthru means that an empty string is returned for these columns. PARAMETERS
o $result_id - The result identifier. If $result_id is 0, the settings apply as default for new results. Note Default for longreadlen is 4096 and $mode defaults to ODBC_BINMODE_RETURN. Handling of binary long columns is also affected by odbc_longreadlen(3). o $mode - Possible values for $mode are: o ODBC_BINMODE_PASSTHRU: Passthru BINARY data o ODBC_BINMODE_RETURN: Return as is o ODBC_BINMODE_CONVERT: Convert to char and return RETURN VALUES
Returns TRUE on success or FALSE on failure. PHP Documentation Group ODBC_BINMODE(3)
