List Public Programs |
PUB(index[,ERR=stmtref])
|
index |
Index in the ADDR table for the entry to be returned. Numeric expression. (Base 0) |
|
stmtref |
Program line number or statement label to which to transfer control. |
String containing information for the program identified by index.
The PUB( ) function returns a string reporting the names, starting addresses and sizes of all programs for which the ADDR directive is active. The information is returned as a character string containing the name and description of each program addressed.
The index indicates the relative program number in the ADDR table. PxPlus updates the table to account for your subsequent ADDR and DROP directives and changes index numbers accordingly. (They are not static.) PxPlus returns Error #41: Invalid integer encountered (range error or non-integer) if no entry in the ADDR table exists for your given index.
This table lists the contents of the string returned by the PUB( ) function:
