I re-wrote Eric's program to collect local macro names
beginning with c, rather than global.
Like Nick Cox, I use locals more often.

There is one non-trivial change that I thought was worth sharing.

*******  Grabbing list of all local macros that start with "c"
local cash "pocket asdf bank"
local check "bank"
local c3 "blah blah"
local c99 "test"
local z1 "ignore this one"

*******get names of all locals 

preserve

 cap log close _all
 log using "macros.txt", text replace
 macro li
 log close _all

 clear
 insheet using macros.txt, tab nonames
**first 6 and last 6 lines are from log, remove those: 
 drop in 1/6  // Eric dropped only 4 lines.  I am not sure why.
 drop in `=_N+1-6'/l  // Using _N-6 would drop 7 lines, 
// including one of the local macros!
**keep if first two letters are _c
keep if substr(v1, 1, 2)=="_c" 
*get names of all locals that start with "c"**
 split v1, p(": ") // splits v1 into v11 (the local name, before the colon) & v12 (the description, after the colon).
 keep v11
 replace v11 = substr(v1,2,.)  // Drop the initial underscore
 levelsof v11, loc(local_c) clean
 global local_c `local_c'
 di `"$local_c"'
restore
********

foreach y of global local_c  {
display "`y'"
}
