The customer uses a different number default format (apostrophe-comma, rather than comma-period), so the decimal function expects a different character.
These values can be set for an ABL session in client startup parameter file.
1. Create a parameter file that ProTop will pick up, e.g. in $PROTOP/etc/custid.pf or $PROTOP/etc/servername.pf.
2. Add the following to your new pf file (for month day year, apostrophe for separator and comma for a decimal marker):
-d mdy
-numsep 44
-numdec 46
