Abstract

inlist2 generates a dummy equal to 1 if varname is equal to the arguments in values(). inlist2 provides a faster way to create multiple "or" statements similarly to inlist, by creating a dummy variable named inlist2 to be used in following step. Inlist2 string values do not require quotation marks (e.g. in case of spaces between parts of the string) so they are faster to write, also, inlist2 does not have a 10 arguments limit for strings or a 250 limit for reals. inlist2 automatically distinguish if the variable is a real or a string, but doesn't allow for commas in string values. Inlist2 does not give error massages if the variable doesn't have one of the values in the list, but one can check replacement is working correctly in the output. Sample conditions (if,in); defines the inlist dummy as a byte and sets it equal to zero when conditions are not satisfied; sets to quiet the replace commands (unless verbose option is on); optimises the dummy creation and sets a default var label.
