system command

[Dennis Malen]

Mark,

Thanks for your response.

Is the problem really the echo command? When I apply that line directly to a 
command line with the use of "echo" in unix it works fine. For your 
information this is a string that executes a TinyTerm file which brings over 
the record number that the user resides in to windows where the scanned 
images reside and pulls up the appropriate record in windows to view the 
scanned images attached to the subject record number.

When executed from the command line it works fine, when executed from the 
system command it does nothing. In addition I have verified that the code 
used in the system command provides visually the correct code with the use 
of msgbox. It displays the code correctly but does not take the user to 
windows via TinyTerm executable file ".cs".
