#emsg := EMSG errorCode
EMSG tableItem
The EMSG command will return a string describing the meaning of the numerical error code errorCode returned by an S_TOOLS-STx command. If a table item (tableItem) is passed instead of an error code, all error descriptions are stored in the table (deleting the previous contents).
// store all error messages in a simple table #tab := new table * EMSG $#tab // show this table to the user showitem $#tab // tidily dispose of the table after use delete /Var #tab
or
// check if command fails and display error message on error #spu := new spu * testspu pa pb pc if '$rc' > 0 em $rc ; SPU creation failed: $(emsg $rc)
