Enters a string in the string table.
When #string appears in a command, it is replaced by its definition from the string table. When #SYS(word) or #UC(word) appears in a command, it is replaced by the value stored in the specified SYSKEY.TAB or User Common word, respectively. See the SYSVAL and UCU commands for more information.
If string's text includes another string name preceded by a single pound sign (#), its value is immediately substituted. If the included string is preceded by two pound signs (##), the value is filled when string is run by typing #string.
Strings with the names KEYF, KEYAF, KEYCF, and KEYSF followed by a number between 1 and 12 (for example, KEYF1, KEYAF2) can be run using the function keys. See Using Strings and Function Keys for more information.
A string name whose first character is a question mark (?) is defined as global. Global strings remain in the table unless you delete them with TD ALL GLOB.
If the string name is a single letter (A-Z), you can run it by typing #string or by pressing Ctrl string.
Do not use X as a string name; McIDAS interprets it as a place holder for default values. Likewise, if a series of strings begins with X (for example, XMAP), you cannot delete them with TD PREFIX X nor run them with REPEAT X 1 TO 1.
Command TL lists string tables; command TD deletes them; command TU is the string table utility. Command ASK1 can also be used to create a string or change its value.
TE LOAD
This entry assigns blanks to the string LOAD.
TE LOAD "IMGDISP GOES/VIS STATION=KMSN
This entry places an IMGDISP command in the string LOAD. To run the command, Type: #LOAD.
TE KEYF2 "MAP H
To run the MAP H command, press the F2 key.
TE NOTE "MAP OF NORTH AMERICA IN SATELLITE PROJECTION
This entry stores the text MAP OF NORTH AMERICA IN SATELLITE PROJECTION in the string NOTE.
TE AAA "TERM L ON
This entry stores the command TERM L ON in the string AAA.
In the compound string example below, remember to define the string replacing the # value before defining the string that uses it.
TE STN "KABQ
The replacement string is #STN.
TE WEATHER "SFCLIST #STN
The actual string stored in WEATHER is SFCLIST KABQ.
TE WEATHER "SFCLIST ##STN
To vary the value in #STN, insert two #s in the string WEATHER. The actual string stored in WEATHER is SFCLIST #STN.
If you change string STN now, the new value is used when WEATHER is run.
TE STN "KMIA
If you enter this change, the system uses SFCLIST KMIA the next time #WEATHER is run.
