According to the current Easytrieve R11.6 User Guide, it seems that the ASCSIGN parameter can be changed at a compile-time and an execution-time. In the "Updating the Table" in the current User Guide, the ASCSIGN parameter is marked at both "Effective at Compile Time" and "Effective at Execution Time".
However, it seems that the ASCSIGN parameter can't be specified in a PARM statement. (In the Language Reference manual, the ASCSIGN parameter is not described as one of the parameters for the PARM statement.)

And the following is described in the same User Gudie for the "Effective at Compile Time" and "Effective at Execution Time".
*************************************
Changes to options become effective at different times when executing previously compiled programs.
Options marked with CT (compile time) become effective at the time the program is compiled. Previously compiled programs are affected by a change in the option only when it is recompiled.
Note: Options marked with ET (execution time) become effective for subsequent executions of CA Easytrieve Report Generator programs. You can only change ET options that the PARM statement overrode at compilation by updating the PARM statement and recompiling. For more information about options and when changes to each option become effective (compile or execution time), see Alphabetical Listing of Options in this chapter.

Can the ASCSIGN parameter be realy changed at execution time? If it can be changed at execution time, how should it be done to change?
