Functional Return | |
- msglength
16-bit signed integer (assigned functional
return) Returns the length of the message (in bytes).
Parameters | |
- filenum
16-bit signed integer by value (required) Passes the file number that specifies the message catalog. - setnum
Positive 16-bit signed integer by value
(required) Passes the message set number within the catalog (>0,<63). - msgnum
Positive 16-bit signed integer by value
(required) Passes the message number within the message set (>0,<32767). - buffer
character array (optional) Returns the assembled message. - buffersize
16-bit signed integer by value (optional) Returns the length of buffer. If buffer is specified, the length is in bytes. If buffer is not specified, returns the length (in bytes) of
the records to be written to the destination file. Default: 72 bytes (For a single-line message, the combined length of the message
number, a blank space separator, and message text must not exceed
the default buffer size of 72 bytes.) - parmask
16-bit signed integer by value (optional) Passes a mask indicating parameter types for param1 through param5. The bit settings are: - Bits
Value/Meaning - 13:3, 10:3, 7:3,
4:3, 1:3 param5-4-3-2-1 type: - 000
String, terminated by an ASCII null (0) - 001
16-bit signed integer - 010
32-bit signed integer by reference - 011
Ignored
- 0:1
value: - 1
Ignore rest of word and parameters param1 through param5 - 0
Rest of word, in 3-bit groupings, specifies parameter
types for param1 through param5
Default: param1 through param5 are ignored.
- param1 through param5
type varies (optional) (NM) Passes the parameter to be inserted into the message.
If parmask is 000 (string), pass the 32-bit address of the array
containing the string. If parmask is 001 (16-bit signed integer), pass a signed 16-bit
integer (a value from -32,768 through 32,767). If parmask is 010 (32-bit signed integer by reference), pass
the 16-bit address of the word identifier that returns the value. (CM) Passes the parameter to be inserted into the message.
If parmask is 000 (string), pass the 16-bit address of the array
containing the string. If parmask is 001 (16-bit signed integer), pass a signed 16-bit
integer (a value from -32,768 through 32,767). If parmask is 010 (16-bit signed integer by reference), pass
the 16-bit address of the word identifier that returns the value. - msgdestination
16-bit signed integer by value (optional) Returns the file number of the message's destination
file (0 or -1=$STDLIST, >2=file number of the destination file). Default: $STDLIST if you do not specify buffer, no file if you do specify buffer. - errornum
16-bit signed integer by reference (optional) Returns one of the following values, indicating the
success or failure of the intrinsic call. - Value
Meaning - 0
Successful - 1
FREADLABEL call on catalog file failed - 2
FREAD call on catalog file failed - 3
Specified setnum not found in catalog - 4
Specified msgnum not found in catalog - 6
Message overflowed buffer (if msgdestination specified, message routed correctly) - 7
Write to destination file failed - 8
Catalog file opened with improper access options - 11
filenum was not specified - 12
setnum was not specified - 13
msgnum was not specified - 14
setnum < 0 was specified - 15
setnum > 62 was specified - 16
msgnum <= 0 was specified - 17
buffersize <= 0 was specified - 18
msgdestination <= -2 was specified - 19
Reference parameter out of bounds
Operation Notes | |
The calling program opens a message catalog, allowing the
insertion parameters supplied by GENMESSAGE. Depending on how the msgdestination and buffer parameters are defined, GENMESSAGE then routes the message to its destination. To
route the message to a file, specify msgdestination. To return the message to a calling program, specify buffer. To do both, specify both msgdestination and buffer. Open the catalog file as a permanent ASCII file with the NOBUF and MULTI access options enabled. Condition Codes | |
- CCE (2)
Request granted. - CCL (1)
Request denied. File system error. - CCG (0)
Request denied. Missing required parameter, invalid
parameter, or invalid file number of catalog or destination file.
