Retrieve data from a file

Hello guys

I want to retrieve two data from a file, like this:
bash-2.03$ cat numtest
123456
123457
bash-2.03$ more ./test_num
#!/bin/bash
num1=
num2=
cnt=1

while read x
do
num${cnt}=$x
cnt=$(($cnt+1))
done <$1
echo $num1 "\n" $num2

But when i executed this script, error popped up
bash-2.03$ ./test_num numtest
./test_num: num1=123456: command not found
./test_num: num2=123457: command not found
\n

Can anyone give any suggestion? Thank you.

scsi_setup_cdb(9F)					   Kernel Functions for Drivers 					scsi_setup_cdb(9F)

NAME
scsi_setup_cdb - setup SCSI command descriptor block (CDB) SYNOPSIS
int scsi_setup_cdb(union scsi_cdb *cdbp, uchar_t cmd, uint_t addr, uint_t cnt, uint_t othr_cdb_data); INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). PARAMETERS
cdbp Pointer to command descriptor block. cmd The first byte of the SCSI group 0, 1, 2, 4, or 5 CDB. addr Pointer to the location of the data. cnt Data transfer length in units defined by the SCSI device type. For sequential devices cnt is the number of bytes. For block devices, cnt is the number of blocks. othr_cdb_data Additional CDB data. DESCRIPTION
scsi_setup_cdb() function initializes a group 0, 1, 2, 4, or 5 type of command descriptor block pointed to by cdbp using cmd, addr, cnt, othr_cdb_data. addr should be set to 0 for commands having no addressing information (for example, group 0 READ command for sequential access devices). othr_cdb_data should be additional CDB data for Group 4 commands; otherwise, it should be set to 0. scsi_setup_cdb() function does not set the LUN bits in CDB[1] as the makecom(9F) functions do. Also, the fixed bit for sequential access device commands is not set. RETURN VALUES
scsi_setup_cdb() returns: 1 Upon success. 0 Upon failure. CONTEXT
These functions can be called from a user or interrupt context. SEE ALSO
