complete McIDAS command to run, including parameters and keywords |
MCEVAL substitutes the correct values for McIDAS strings specified in command, then runs the command. Use MCEVAL if you need to update a McIDAS string and use its new value in a concatenated command (separated by a semicolon). See the examples below. Also use MCEVAL if you run McIDAS-X commands with McIDAS string substitutions from the Unix shell. See Appendix H, Running Commands Outside a McIDAS-X Session, for more information.
ASK1 LL {Center latitude and longitude:}; MCEVAL IMGDISP GOES/VIS LATLON=##LL
This entry runs an ASK1 command that prompts you for a value to enter for the string LL. After you type a value for string LL, the IMGDISP command uses it to center the image at that location.
te.k STATION \"KSEA; mceval.k SFCLIST \#STATION 3
This entry, when typed from the Unix shell, runs a TE command that sets the value of the string STATION to KSEA. It then runs the SFCLIST command, using the value of the string in a SFCLIST command. That is, it runs the command SFCLIST KSEA 3.
