st: Uppercase arguments for programs |

Dear Statalist, Is there a way to use uppercase arguments for programs? The use of uppercase letters to designate the required portion of the argument's name seems to prevent this. Consider the following simple example: --- begin example code --- cap program drop uppercase_argument program define uppercase_argument syntax, K(integer) di "there are `K' right-hand-side variables" di "there are `k' right-hand-side variables" local K = `k' di "there are `K' right-hand-side variables" end capture noisily uppercase_argument, K(3) di _rc capture noisily uppercase_argument, k(3) --- end example code --- This yields the following output: --- begin output --- . capture noisily uppercase_argument, K(3) option k() required . di _rc 198 . . capture noisily uppercase_argument, k(3) there are right-hand-side variables there are 3 right-hand-side variables there are 3 right-hand-side variables --- end output --- There is a workaround that involves creating new local macros within the program, e.g. in the above a line like local K = `k' but this is tedious and leads to errors, both from simple typos and from Alice's White Knight "what the name of the song is called" type mistakes confounding the macro with the name of the macro, etc. Many thanks in advance for any suggestions. - BL * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
