Hi Iliana, re: > When reading the contents of a MD file with PTLIST, how do I direct the > output to a text/ASCII file? All output from McIDAS commands is controlled by the DEV= keyword. Here is the relevant portion of the McIDAS-X User's Guide for reference: Unidata HomePage http://www.unidata.ucar.edu Software -> McIDAS http://www.unidata.ucar.edu/software/mcidas Documentation http://www.unidata.ucar.edu/software/mcidas/#documentation The user guide is the primary documentation for McIDAS http://www.unidata.ucar.edu/software/mcidas/current/users_guide/toc.html Appendicies -> A - Global Keywords http://www.unidata.ucar.edu/software/mcidas/current/users_guide/GlobalKeywords.html DEV - routes text output to a device http://www.unidata.ucar.edu/software/mcidas/current/users_guide/GlobalKeywordsDEV.html re: > I've done that in the past, but I had forgotten the exact command syntax. The DEV= global keyword is something that is easy to forget if you are not using McIDAS ll of the time. Simple Example: PTLIST RTPTSRC/SFCHOURLY PARAM=DAY TIME ID LAT LON T[C] TD[C] DIR SPD FORMAT=X X X F6.2 F7.2 F54.1 F4.1 SELECT='CO RO' NUM=10 DEV=T ptlist.txt This will create the file 'ptlist.txt' in the first writable directory in your MCPATH which in Unidata McIDAS-X is usually ~/mcidas/data for users other than 'mcidas' and ~mcidas/workdata for the user 'mcidas'. re: > Many thanks, No worries.
