getting further...the mainframe program is getting all my messages from my C program on the as400 but it is getting an error of wrong format. they are using the convert in the GMO, and I never did set my MQMD.Format so I guess it defaults to NONE. anyway I wanted to add the line in. msgDesc.Format = MQFMT_STRING; but when im compiling it i keep getting this one error, and it adds in the line below it on 1347, tried that line but no luck--what am i doing wrong?? thanks
here is the spool file from the compilation
1347 | MsgDesc.Format = MQFMT_STRING;
1347 11 + MsgDesc.Format = "MQSTR ";
===========> ....a......................................................
*=ERROR===========> a - CZM0114 Operand must be a modifiable lvalue.
1348 12 | MsgDesc.Priority = 1;
1349 13 | MsgDesc.Persistence = MQPER_PERSISTENT; |

Assuming C programming language ....
The definition of the MQMD structure Format field is usually
char Format[8];
This means that the field is an 8 byte character array. To set the value of this field to something, you can't simply assign it like a variable, instead, you must copy the contents of what you would like the format field to contain.
For example:
memcpy(Format, MQFMT_STRING,  ; |

Thanks alot. that helped alot. Im new to MQ programming and I havent done too much coding in C but thats what im asked to do right now, I prefer using java and my boss will likely let us in the future. I cant wait to learn all this MQ stuff in Java.
I will say the PCF command stuff is extremely hard to me and is way over my head right now. wish me luck |
