DESCRIPTION

Cq_fgval[ird] is an integer, real, or double function which returns the
integer, real, or double value of the requested field or keyword as its
function value.

Cq_fga[ird] returns an integer, real, or double array for the requested
field.  Cq_fga[ird] is an integer function which returns the number of elements
in the retrieved array as its function value.

Cq_fg[wrd/str/text] returns the next word, the entire string,  or the
number of lines in the requested keyword. Cq_fgtext is an integer function
which returns the number of lines in the returned text as its functions
value.

NOTES
The cqget routines are used to read keywords or fields in the current catalog
or survey directly. The routines cq_setcat or cq_setcatn must be called before
the cqget routines can be used.

The cqget routines must be error checked to avoid task termination.

EXAMPLES

Sample catalog configuration file  record.

.nf

.fi

Example 1: To fetch the query field which includes embedded blanks use cq_fgstr.

.nf
call cq_fgstr (cq, "query", buffer, SZ_LINE)
.fi

Example 2: To fetch the type field use cq_fgwrd.

.nf
call cq_fgwrd (cq, "type", buffer, SZ_LINE)
.fi

Example 3: To determine the number of query parameters.

.nf
nquery = cq_fgeti (cq, "nquery")
.fi

Example4: To return a text array which follows a numerically valued parameter.

.nf
nquery = cq_fgeti (cq, "nquery")
nlines = cq_fgtext (cq, "nquery", buffer, nquery * SZ_LINE)
.fi
