ASL

Details

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.

ASL only prints a summary of information for each segment on file. To print the actual contents of these segments, run the following programs:

VECREP: prints report on vector segment (type 116)
CSR: prints report on signature segment (type 121)
ORBITWR: prints report on orbit segment (type 160)
ARRWRIT: prints text file of array data (type 181)
GCPREP: prints report on ground control points (type 213 or 214 or 215)

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

where:

Num: is the segment number
Typ: is the 3-letter segment type code. Available codes include:
- Bit: bitmap segment
- GCP: ground-control point segment
- LUT: lookup table segment
- PCT: pseudocolor table segment
- Sig: signature segment
- Tex: text segment
- Vec: vector segment
Seg-Description: is the segment 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

where:

num: is the segment number
hhmm dd-mm-yy: is the time and date that the segment was last written to
xxx...xxx: is a description of the segment contents
ttt: is 3-digit segment type number
aaa.aaa: is the description of the segment type

The following segment type numbers and description are possible:

101: bitmap
116: vector/polygon
121: signature
140: text
160: orbit
170: lookup table
171: pseudocolor table
172: lookup table
173: pseudocolor table
180: binary
181: array of numbers
214: ground-control points

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:
    (first  line of history)
    (second line of history)
    . . .
    (eighth line of history)

FULL listings also include segment type dependent information:

Vector (type 116): Units, and Bounds
GCP (type 214): Input Units, Output Units, and Number of GCPS

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