MHELP optionsparameters are dumped in hexadecimal; system parameters are dumped inEBCDIC. The full value of SETC variables or parameters is dumped inhexadecimal.MHELP B'10000000' or MHELP 128, MHELP Suppression:This option suppresses all currently active MHELP options.MHELP Control on &SYSNDX:The maximum value of the &SYSNDX system variable can be controlled bythe MHELP instruction. The limit is set by specifying a number in theoperand of the MHELP instruction that is not one of the MHELP codesdefined above, and is in the following number ranges:v 256 to 65535MHELP operand mappingv Most numbers in the range 65792 to 9999999. Refer to MHELP operandmapping below for details.When the &SYSNDX limit is reached, message ASMA013S ACTR counterexceeded is issued, and the assembler in effect ignores all further macrocalls.The MHELP operand field is actually mapped into a fullword. The predefinedMHELP codes correspond to the fourth byte of this fullword, while the &SYSNDXlimit is controlled by setting any bit in the third byte to 1. If all bits in the thirdbyte are 0, then the &SYSNDX limit is not set.The bit settings for bytes 3 and 4 are shown in Table 62.Table 62. &SYSNDX Control BitsByteDescriptionByte 3 - &SYSNDX control 1... ....
