[Gambas-user] Hours of strugglin with EXEC and SHELL

Fri Jan 25 15:34:30 CET 2008

in stead of using 2 command you can alsdo do

$ ls /tmp

The output can be stored in a variable using the TO operant

SHELL "ls /tmp" TO sOutput
PRINT sOutput

jaap

PS
Yesterday I send two mails, but it seams nobody got them. mailinglist error? Fortunately other people gave the same advise, so the people in question were helped. Please confirm this mail is recieved...
