If so, then your design is wrong. If you }simply wish to run the same program with two different values of DBDATE, }then use something like a shell script to set the variable and then call }your 4GL program. Further, even if you manage to get the environment set correctly (it can be done -- I wrote some code to do that and it is in the CGI stuff that is/was available from http://www.informix.com) you then start to run foul of the problem that many of the environment variables used by a program are read just once, so changes after the program first reads the value have no effect.
