Beware of functions with string parameter
Functions that have only one string as parameter IGNORE the parenthesis. This often leads to unwanted and unexpected side effects.
A famous example of this behavior:
string sA = "upper" string sB = "lower" print upper(sA) " " sB
instead of what was intended:
workaround, use parenthesis:
print (upper(sA)) " " sB
Memory footprint (string table)
Avoid string concatenation, like:
"stra" " strb"
it adds entries to the global string table which keeps increasing in size. There is no way to free entries from the global string table. Only closing a DOORS session will end up in freeing the memory.
