OPSYN Instruction
,ERROR, SEV 1
An asterisk in the severity code subfield causes the message and the asterisk
to be generated as a comment statement.
Example:
MNOTE ,'NO ERROR'
The generated result is:
,NO ERROR
If the severity code subfield is omitted, including the comma separating it from
the message, the assembler generates the message as a comment statement.
Notes:
Example:
MNOTE 'NO ERROR'
The generated result is:
NO ERROR
1. An MNOTE instruction causes a message to be printed, if the current PRINT
option is ON, even if the PRINT NOGEN option is specified.
2. The statement number of the message generated from an MNOTE instruction
with a severity code is listed among any other error messages for the current
source module. However, the message is printed only if the severity code
specified is greater than or equal to the severity code nnn specified in the
FLAG(nnn) assembler option.
3. The statement number of the comments generated from an MNOTE instruction
without a severity code is not listed among other error messages.
OPSYN Instruction
The OPSYN instruction defines or deletes symbolic operation codes.
The OPSYN instruction has two formats. The first format defines a new operation
code to represent an existing operation code, or to redefine an existing operation
code for:
Machine and extended mnemonic branch instructions
Assembler instructions, including conditional assembly instructions
Macro instructions
Define Operation Code

The second format deletes an existing operation code for:
Machine and extended mnemonic branch instructions
Assembler instructions, including conditional assembly instructions
Macro instructions
