FILE
Specifies the name of the PCIDSK file containing the segments to summarize.
LTYP
Specifies the type for the summary list.
Brief: produces a summary of each segment including the segment number, its type, and the segment name.
For more information, see Brief List in the Details section.
Short: produces a summary of each segment including the segment number, its name, the time and date the segment was last written to, a description of the segment, its type, and a description of the segment type.
For more information, see Short List in the Details section.
Full: produces a summary of each segment all available information for that segment.
For more information, see Full List in the Details section.
ASLT
Optionally specifies a 3-digit segment type code for segments to include in the list.
For example, ASLT=101 lists all bitmap segments.

ASL lists information about specified segments stored on the database (FILE). ASL compiles three types of reports: Brief, Short, and Full (defined by LTYP). By default, ASL produces a Short listing of all segments on the database file. Subsets of segments can be listed by specifying appropriate values for ASLT.
In addition, ASL saves, in the IMSTAT output parameter, the segment numbers found that match conditions set by ASLT.
Brief List
When the BRIEF listing option is selected, each segment is listed with the following information:
Num:[Typ] Seg-Description
Short List
When the SHORT listing option is selected, each segment is listed with the following information:
num: Type:ttt[aaa...aaa] Last Update: yyyy-mm-dd
Contents: xxxxxxxx
Full List
When the FULL listing option is selected, each segment is listed with the following information:
Number:xxxx Type:xxx [description]
Creation: yyyy-mm-dd Last Update: yyyy-mm-dd
Contents: xxxxxx
[segment type dependent information]
History:

Signature, Lookup Table, and Pseudocolor FULL listings do not contain segment type-dependent information.
