Syntax
For C:
#include "usrdecs" short result; short col_idx; char col_name[36]; short max_name_len, short source_or_target; result = GET_COLUMN_NAME(col_idx, col_name, max_name_len, source_or_target);
For TAL:
?source usrdect int result; int col_idx; string .ext column_name; int max_name_len; int source_or_target; result := GET_COLUMN_NAME (col_idx, col_name, max_name_len, source_or_target);
For COBOL:
?CONSULT =EXTRACT (or =REPLICAT) 01 result PIC S9(4) COMP. 01 col-idx PIC S9(4) COMP. 01 col-name PIC x(36). 01 max-name-len PIC S9(4) COMP. ENTER C "GET_COLUMN_NAME" using col-idx, col-name, max-name-len, source-or-target giving result.
