self programming IDL needed? [message #7355]

Hello,

on my adventures with execute I discoverd:

it only accepts 65 commas (ie parameters) in its string

i tried execute("print,a,a,a,a,a,a,......") for this.

if you use a variable for the content it may be different,
i will have to research...

the limit 131 chars is not found on IDL 4.0.1. I successfully
processed strings of the length 1738 chars.

----------------------
to my questions

i want to define a REALLY NEW variable (names depends on other
variables!

Imagine:

i=0L
for i=1,20 do begin
a="testname_"+string(i)
b=a+'=findgen(i)'
out=execute{b}
endfor
help
print,"well? all vars defined?"

It is obvious that i CANNOT declare the variable names eg with another
execute... (watch out for the warning in execute-manpage)

My idea in this was to programm a new file with idl in front...:

openw,lun,"dyndef.pro"
printf,lun,"pro dyndef"
for i=1,20 do begin
printf,lun,"testname_"+string(i)+"=BYTE(0)
endfor
printf,lun,"exit"

; now call my dynamic definitions procedure...
dyndef

will this work our is there a more elegant way to declare the vars?

any hint wanted...
