global a,b,c
and on a particular card I *add* another global, e.g.,:
global a,b,c,d
then d often is undeclared (i.e., not even empty)
Two cures, but only one works absolutely:
1. put the new global on a new global line: global a,b,c global d -- sometimes still fails
2. before using in the first cd script put some value (e.g., 0) into the new global:
put 0 into d -- fix global bug
in this latter case, d now functions correctly as a true global
