Adding entry into crontab in ksh program

Hi falks,

I have the following ksh function ,which adding entry to crontab during ksh program running:
{
print "Go\c" >/dev/null 2>&1
print '0 0 * * * su - ias -c "/home/orca/core-${SCHEMA_NAME}/CLI/cleanup_BRMS.ksh"\c' >/dev/null 2>&1
print "\033:wq!" >/dev/null 2>&1
} | \crontab -e >/dev/null 2>&1

The problem with this function that the parameter ${SCHEMA_NAME} was not substituted with the real value.
The crontab got the following entry:
0 0 * * * su - ias -c "/home/orca/core-${SCHEMA_NAME}/CLI/cleanup_BRMS.ksh

my question:
1. Why the parameter was not substituted with a value?
2. Is there another way to insert values into crontab during running of ksh program?

Thanks in advance,
Nir
