Re: 4GL: space allocation for temp. strings

Thus, if you are calling several functions that pass quite a few parameters around, you can run out of space to hold them. The ugly solution that I've been forced to use in the past to get around this is to use global variables for some of the parameters. Not exactly textbook programming practice, but it works ...
