Text Substitution and Script

Sed Wizards,

I have a script that has worked well in a previous
job. However, the same script doesn't work in my
current SunOS: 5.8 setting. First there is a
difference in the way I call the script in my current
environment:

/home/myname/ 127> source myscript

previously I would simply do this as

/home/myname/ 127> myscript

What may be some of the system set-up differences that
necessitates the use of "source"? This difference per
se is not a big thing. Why does the following script
fail which used to work before? It does not recognize
"for" and "do".

cupsas01 /wwbdm/clin/proj/ca/183/maclib/dev/scripts/
124> more change1.script 
#!/bin/sh 
# Perform a global search and replace operation on all
*.sas files in this directory 

for sas_filename in *.sas 
   do 
       sed 's/180/183/g' $sas_filename > temp_filename

       mv -f temp_filename $sas_filename 
   done 

Here is the how the script is called and the messages.

cupsas01 /wwbdm/clin/proj/ca/183/maclib/dev/scripts/
125> source change1.script 
for: Command not found. 
do: Command not found. 
sas_filename: Undefined variable.

Thanks

Venky Chakravarthy
