190 CHAPTER 16. DATA STRUCTURE MANIPULATION
16.1.4 structure get
Function to return a value of a specified field of a structure. Following from the example in
Section 16.1.3, the value of the field NAME is extracted.
CIA> help, scd_get( ’name’, ’CSCD143006010105_96080110071423’ ), ack
STRING = ’EARTH’
ACK INT = 1
See Section 2.4 for restrictions of use.
16.1.5 structure write
Procedure to write a specified structure to a file. The filename will be the name of the structure
with .cub appended. When using sscd write and ssad write the entire set of SCDs or SADs
are written to disk. In the example below a single SCD is written to disk in the directory
product dir (see Section 17.1.1).
CIA> scd_write, ’CSCD143006010105_96080110071423’, dir=scd_dir, ack=ack
CIA> help, ack
ACK INT = 1
See Section 2.4 for restrictions of use.
16.1.6 structure read
Function to read a named structure from disk. A pointer to the structure is returned. Our
example below follows from that of Section 16.1.5.
CIA> scd = scd_read( ’CSCD143006010105_96080110071423’, dir=scd_dir, ack=ack )
16.1.7 structure list
Function to return the a list of structures of type structure in memory. Following from Section
16.1.6 our example lists the SCDs in memory.
CIA> print, scd_list( num=no_scds, ack=ack )
CSCD143006010105_96080110071423
etc...
CIA> help, no_scds, ack
NO_SCDS INT = 42
ACK INT = 1
The keyword num returns the number of scds found.
