SNAP [loc][,nwds][#pgm][-sloc]
snap 0121 - snap location 121 octal in TSS snap .crlal,64#0 - snap 64 words of the .CRLAL table in GCOS snap .sacty#12 - snap the activity name of program 12
After snapping the first request, the program prompts with a ? and waits for more requests. A carriage return terminates SNAP.
GCOS and TSS communications symbols may be entered as location address constants. They are current for release 3/i GCOS (e.g. snap .tcnou).
Numbers are treated as decimal unless they start with a zero, in which case they are treated as octal (and so may not include an 8 or 9). All numbers will be handled as octal if you type in "octal" in response to an input request.
There are also eight "registers", named "x0,x1,...x7, which can be set, inspected, or used to modify a snap.
The various forms of snap commands permitted in prompt mode are shown below. <loc> may be either a symbol (like .CRLAL) or an octal or decimal constant.
form example description ---- ------- ----------- <loc> .crlal snap given location <loc>,<nwds> .crlal,64 snap 64 words starting at .CRLAL <loc>,x<n> .crlal,x5 snap word at .CRLAL + x5 <loc>-<endloc> 02771-02775 snap range of words
The above forms may be suffixed by #<nn> to set the program number.
#<nn> #0 set program number 0 x<n>=<loc> x5=5 set value of a register x<n> x5 show value of a register x x show value of all regs !<TSS command> !wmi issue TSS command octal octal all numbers to be taken as octal decimal deci take nums without leading zeroes as decimal
