You seem to imply that the verbs above don't provide the correct
functionality?
They seem to do the job to me. What am I missing?
load 'c:\program files\j601\addons\web\jhp\jhp.ijs'
]CGIKEYS=: ;:'abc lbl abd abc abcd lbl'
+---+---+---+---+----+---+
|abc|lbl|abd|abc|abcd|lbl|
+---+---+---+---+----+---+
]CGIVALS=. ;:'v11 v21 v31 v12 v41 v22'
+---+---+---+---+---+---+
|v11|v21|v31|v12|v41|v22|
+---+---+---+---+---+---+
qparamList 'abc'
+---+---+
|v11|v12|
+---+---+
qparamList 'lbl'
+---+---+
|v21|v22|
+---+---+
qparamPrefix 'ab'
+----+---+
|abc |v11|
+----+---+
|abd |v31|
+----+---+
|abc |v12|
+----+---+
|abcd|v41|
+----+---+
qparamPrefix 'abc'
+----+---+
|abc |v11|
+----+---+
|abc |v12|
+----+---+
|abcd|v41|
+----+---+
qparamPrefix 'a'
NB. The qparamPrefix needs a tweak to cope with the singleton prefix
qparamPrefix ,'a'
+----+---+
|abc |v11|
+----+---+
|abd |v31|
+----+---+
|abc |v12|
+----+---+
|abcd|v41|
+----+---+

Sounds sensible
