StartsWith Function

Format
b = startswith(prefix, source);
Description
The startswith function determines whether the string expression source begins with the string expression prefix. It is the same as checking if:
pos(prefix, source) = 1
In addition to standalone use as a function, startswith can be used when specifying dictionary access parameters.
Return Value
The function returns a logical value of 1 (true) if the source string starts with the prefix and 0 (false) otherwise.
Examples
if startswith("9999", MENU_GEOCODE_SELECTION) then
   
errmsg("Are you sure that you want to continue in training mode?")
   
select("Yes", continue, "No", reenter);
endif;
