FRQDRV
Drives loop on frequencies defined on FREQi Bulk Data entries
FRQDRV Drives loop on frequencies defined on FREQi Bulk Data entries
Drives loop on frequencies defined on FREQi Bulk Data entries and is intended for
frequency-dependent element processing.
Format:
FRQDRV CASECC,FRL/
FRLI/
S,N,FRQLOOP/S,N,FREQVAL $
Input Data Blocks:
CASECC Table of Case Control command images.
FRL Frequency response list
Output Data Blocks:
FRLI Frequency response list for a single frequency.
Parameters:
FRQLOOP Input/output-integer-no default. Frequency loop counter. On input,
FRQLOOP should be initialized to 0 before the loop. On output,
FRQLOOP is incremented by one and at the last frequency, FRQLOOP
is negated. For example, if the fifth frequency is the last then FRQLOOP
is output as -5.
FREQVAL Output-real-no default. Frequency value for frequency dependent
element generation.
Example:
TYPE PARM,,I,N,FRQLOOP=0 $
DO WHILE ( FRQLOOP>=0 ) $
