This Natural profile parameter applies to batch mode only.
CMSYNIN is used for the batch input file. It
                          contains Natural commands and data to be read by INPUT statements
                          during execution of Natural programs (optionally). The number of characters
                          actually processed is restricted to 512 characters per line.
               
Note:
 If the file name or path assigned to this parameter contains
                             special characters, e.g. backslash (\) or spaces, the entire string must be
                             enclosed in double quotes, see example below.
