$TableC
Information provided by TABLEC command
Most Sirius $functions have been deprecated in favor of Object Oriented methods. There is no OO equivalent for the $TableC function, but you can achieve the same results by capturing the output of a TABLEC command execute in a Daemon request into a StringList.
This function allows retrieval of the information provided in the TABLEC command from a User Language program.
The $TableC function accepts two arguments and returns a number indicating the success of the function. It is also callable .
The first argument, which is required, is a string identifying an image to receive returned data. This image should have the following format :
IMAGE TABLEC_IMAGE FILE_NAME IS STRING LEN 8 SLOTS_TOTAL IS BINARY LEN 4 SLOTS_USED IS BINARY LEN 4 SLOTS_PCT IS BINARY LEN 4 * FOLLOWING FIELDS SET TO ZERO FOR PRE-8.1 FILES PROP_COUNT IS BINARY LEN 4 PAGE_SPILL IS BINARY LEN 4 PROP_OVFL IS BINARY LEN 4 PROP_SPCT IS BINARY LEN 4 END IMAGE
The second argument is the name of the file on which the $TableC function should operate. If this argument is not specified the default file at compilation time is used by $TableC.
