Hi, John!
Here's my code up to the map-flat point.
: num>str ( n -- string )
number>string 2 CHAR: 0 pad-head ;
: idx[] ( n -- string )
num>str "[" "]" surround ;
: idx ( name n -- seq )
iota [ idx[] dupd append ] map nip ;
: R2460 ( -- seq )
{ "LL" "DL" "FWL" "BLL" "ULL" "LR" "VP" "MP" "LP" "AT" "VT" "SS" } [ 64 idx ]
map-flat ;
What I need is a list of strings containing
"LL[00]"
"LL[01]"
"LL[02]"
...
"LL[63]"
"DL[00]"
"DL[01]"
...
"DL[63]"
"FWL[00]"
"FWL[00]"
...
"FWL[63]"
...
"SS[63]"
This list after some more transformations becomes an XML configuration file
for Matrikon OPC Explorer, and R2460 is one of the device types supported by my
configuration generator in Factor.
